Hardware Certification Kit (HCK) Certifying USB Audio drivers. KS Position Test doesn't run

I'm running the Hardware Certification Test to certify our USB audio APOs. I'm currently certifying on Win8.1N 32bit. The KS Position Test runs, but is marked as failed. The Error says:

USB Audio on 27" Cinema Display doesn't work on 27" iMac

I have a new 27 inch display paired with my 27 iMac (i7), When selecting "Display Audio" as a sound output device it does nothing and switches right back to Headphone port. And I have installed the 27 inch update before the display arrived... does anyone else have the same issue with their display?
Thanks,
/b

I had this problem with USB SoundSticks. Here is your solution:
Delete the com.apple.soundpref.plist from the *MAIN LIBRARY>PREFERENCES* - (not the users library PREFERENCE folder).
Again, in the same *MAIN LIBRARY>PREFERENCES* folder, go into the AUDIO folder and delete com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist
Reselect the sound device you want as your default in the Sound Preference Pane.
Restart your computer.
And PRESTO!!!! works like a dream.

USB Audio issues - Philips SpeechMike - Fusion v3.1.2 on 10.6.6

Hello all.
Sorry, I know this is a cross-post on the VMware Fusion forums too... but the issue seems to be Apple related based on the 10.6.3 bugfix.
I am at a loss here and hope someone has a few pointers.
We use the Philips speechmike devices for dictation in windows via dragon. Previously we were running XP pro sp3 but are now installing Win7 pro. As part of this, we have upgraded to 10.6.6 and our fusion to v3.1.2.
Since this point, our speechmikes are not working properly under either the XP or Win7 machines.
Once the device is attached, whatever we do first (playback or record) is what the device will do. For example, if we plug it in and the 'ta-da' audio plays for a new USB device, the speechmike will only play audio and the mic will not work. If we disable playback by muting the audio output, disconnect and reconnect the speechmike, we can now record but attempts to unmute and playback audio throw errors.
This behavior is very similar to that of an IRQ conflict with the USB device...
I know about the USB problem that existed from 10.6.0 - 10.6.3, but the scratchyness in the playback audio is lightyears better than this.
FYI... We can't use the audio device under Mac OS since the control buttons on the speechmike will not translate through to the Windows OS. These are a requirement.
Help please!
Thanks in advance. -Peter.

+ Fusion v3.1.2

USB audio DAC stops working after suspend

I didn't update my mediacenter running arch for a few months so I figured i'd reinstall it because of the filesystem, /lib and grub changes. Now after reinstalling I'm running into the issue that my USB audio DAC stops working after a suspend.
After a suspend speaker-test gives me the following error:
[user@mediacenter ~]$ speaker-test -c 2
speaker-test 1.0.25
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1068:(snd_pcm_dmix_open) unable to open slave
Playback open error: -77,File descriptor in bad state
I've tried replugging my DAC and restarting ALSA, without any success. I have to reboot to get sound again.

Yes I am suspecting the kernel as well. I'll try to change some options in XBMC to maybe get this working, and if not I'll see how far I can downgrade with the kernel. My last installation was a few months old so I hope it broke not that long ago.

USB audio hardware: what works with iBook 366 clam and OSX 2.8?

I just bought a Behringer UAC202 USB audio interface. My iBook will recognize that it is attached and will give me audio 'out' settings, but it will not configure any audio 'in' settings. It works fine on my iBook G4 with OSX 4.11 however.
Is this a Behringer problem? Do I need to use OSX Panther on the old iBook? Is there a problem with the old clamshell's as far as USB audio in?
Anyone know a cheap USB audio hardware that works in this case? I want to dedicate this great old machine to some easy audio useage.... using the Polar RAM looper instrument in Digital Performer..... and nothing else..... I'm not recording audio to my hard drive..... just want to get audio in and out of the iBook to and from Digital Performer.
Thanks!

Driver support in Panther is pretty limited with regards to newer hardware as far as i've experienced. If there isn't any drivers offered, either by the company or via third party, then you may be stuck.
The only way that i get audio in on my Blueberry iBook is with the Apple iMic that i picked up at an Apple Store a few years ago. It works fine under panther, tiger and leopard.
Good Luck

Adobe Audition 3.0 "Audio Hardware Settings" for USB Audio Interface HELP!

Hi guys.
I’m after some help in the internal settings of Adobe Audition 3.0 whilst I’m trying to run my condenser mic through my ART USB Dual Pre.
I have the USB Dual Pre all set up in my Windows 7 set up (it automatically becomes the default recording device when it’s plugged in), phantom power enabled, XLR cable plugged into the right socket of the two available (is there any difference? I’m just recording voice tracking for radio announcements), headphones plugged into the monitoring jack at the back. Levels are turned up enough that they will pick up the noise, if there was any.
I go to the “edit” tab in Adobe Audition 3.0, hit record and nothing comes up. I’m not getting any sound at all registered on the computer. I’ve downloaded and installed Asio4All, but can’t for the life of me figure out the configuration within the “Edit > Audio Hardware Setup” to make the damn thing pick up my voice. There’s mention of Audio Drivers (Asio4All or Audition 3.0 Windows Sound), USB Audio Codecs, Input/Output… it’s enough to make a man who’s not very good at this sort of thing cry (ie. Me).
Could anybody help a body out, please? I think I’ve done everything right except the configuration within Audition itself. A helping hand would be GREATLY appreciated.
Thanks so much!

Hey there,
Thanks for your reply! I'm not too good at describing what I'm doing, so I've taken screenshots of all the options in "Edit > Audio Hardware Settings" under Edit View and Multitrack view. They include both Audio Drivers available (which were Asio4All and Audition 3.0 Windows Sound) and the associated Default Input/Output options, as well as the Audio Driver control panels and the options that were checked/unchecked on them.
If anybody could tell me how to configure this so I can actually record from my USB Dual Pre, that would be one better than I can do!
Thanks heaps.

Pancenter,
Thanks for the response, but I do not have a midi interface. I am using a midi to usb connector cable, thus bypassing the need for a Midi interface.
The Mac reads the USB cable as a midi device, but not the keyboard that I am trying to use as a controller. I have tried it with my korg sp 300 and with my Nord Electro 2.
Thoughts?
Thanks,
Tristan
Tristan...
This is what you have, correct?
http://www.alesis.com/usbmidicable
This from Alesis..
"The AudioLink Series USB cable receives and outputs MIDI signal thanks to its internal interface. The USB-MIDI Cable connects plug-and-play to your Mac or PC for an all-in-one USB-MIDI solution."
Notice, -internal interface-. What you have is a simple USB MIDI Interface. Most MIDI interfaces are USB.
My point is (was), MIDI OUT of the Korg goes to the connector marked MIDI IN on the Alesis, those new to MIDI often get this wrong.

[Vox] MSI VOX TV BOX USB 2.0 problem with audio drivers compatibility

Ok,let's go...
I have a DELL Latitude d510 laptop with a centrino 1.73 GHz procesor and a soundcard supported by Sigmatel software Sigmatel C-Major audio.I bought MSI VOX TV BOX USB 2.0 and tried to install it on my lap top.Yes,I had problems with SP2 on my XP and the MSIVPS software from the instalation CD was crashing every time I tried to start it,but I solved those problems by downloading the latest drivers and the 3.xx version of MSIPVS.But...I still have a problem with audio.To be precise it seems that my audio drivers are incompatible with the VOX drivers.So now I have video but I don't have audio.Also I installed the tv card on my desktop machine and it worked like a charm(everything workes:audio,video,the old MSIPVS which I like better than the new one cause it supports my remote,has better way of managing scanned channels,e.t.c ,but I have USB 1.1 on my MB so the image quality is very poor).I did a lot of experimenting,for example i uninstaled my audio drivers(that Sigmatel C-Major thing),and installed the old MSIVPS and guess what...IT WORKED but there is no use from this cause I don't have audio On the other hand if I have everything installed then in the MSIVPS (the 3.xx version not the old one) under audio I get CD Player as an input audio device(what happened with microphone...?).To cut the long story short I tried a bunch of things and still no audio.Is there any other case of DELL audio software-VOX incompatibility?Any ideas,or solutions?

thank you for answering me. y have no pci card working, only usb 2.0 and sata devices. also, the MSI geforce 9600gt PExp 2.0 gpu. the only usb 2.0 devices which work, are the flash (pen) drives, keyboard and mouse. but no way that the WLAn adapter and TVcapture, both usb 2.0 work.i've tested them front side and rear side and is the same failure: if i use a pendrive, works ok. if i insert the wlan or the tv capture stop work as the 2.0 and a advertising window tell me to change to a 2.0 port, means the ports are working slower, at 1.1. i still have the other PC, built on the MSI K9N4-slif mobo, tested them and both devices work at perfection. i have 2 screenshots to show you:
this, is the device manager (sorry, in spanish but you understand that's about the nVIDIA EHCI USB 2.0 controller. the 2nd one seems to be more sensitive (works worth) then the first one. when the tvcapture begin work, then fails, i'm trying to update this controller, does it ok but then the devicemanager-window freeze. i must stroke the "enter" key to "accept" / finish the update. then, fails again:
the other one is from everest corporate edition:
both drivers marked with purple colour!
i think i should update this Win XP drivers, but how? the usbport.inf file (C:\Windows\inf) don't change anything. i don't want to switch xp to vista, i'm happy whit it.
i'm thinking also on another possibility: could be an energy failure? some usb devices, like the big usb flash dives. 250-320gb, fail because the 5v/usb are receiving it's not enough. could be, but that means this mobo has no solution and i'll loose my money.
thank you very much and i'll stay alert of your suggestions. by

A quick primer on audio drivers, devices, and latency

This information has come from Durin, Adobe staffer:
Hi everyone,
A common question that comes up in these forums over and over has to do with recording latency, audio drivers, and device formats. I'm going to provide a brief overview of the different types of devices, how they interface with the computer and Audition, and steps to maximize performance and minimize the latency inherent in computer audio.
First, a few definitions:
Monitoring: listening to existing audio while simultaneously recording new audio.
Sample: The value of each individual bit of audio digitized by the audio device. Typically, the audio device measures the incoming signal 44,100 or 48,000 times every second.
Buffer Size: The "bucket" where samples are placed before being passed to the destination. An audio application will collect a buffers-worth of samples before feeding it to the audio device for playback. An audio device will collect a buffers-worth of samples before feeding it to the audio device when recording. Buffers are typically measured in Samples (command values being 64, 128, 512, 1024, 2048...) or milliseconds which is simply a calculation based on the device sample rate and buffer size.
Latency: The time span that occurs between providing an input signal into an audio device (through a microphone, keyboard, guitar input, etc) and when each buffers-worth of that signal is provided to the audio application. It also refers to the other direction, where the output audio signal is sent from the audio application to the audio device for playback. When recording while monitoring, the overall perceived latency can often be double the device buffer size.
ASIO, MME, CoreAudio: These are audio driver models, which simply specify the manner in which an audio application and audio device communicate. Apple Mac systems use CoreAudio almost exclusively which provides for low buffer sizes and the ability to mix and match different devices (called an Aggregate Device.) MME and ASIO are mostly Windows-exclusive driver models, and provide different methods of communicating between application and device. MME drivers allow the operating system itself to act as a go-between and are generally slower as they rely upon higher buffer sizes and have to pass through multiple processes on the computer before being sent to the audio device. ASIO drivers provide an audio application direct communication with the hardware, bypassing the operating system. This allows for much lower latency while being limited in an applications ability to access multiple devices simultaneously, or share a device channel with another application.
Dropouts: Missing audio data as a result of being unable to process an audio stream fast enough to keep up with the buffer size. Generally, dropouts occur when an audio application cannot process effects and mix tracks together quickly enough to fill the device buffer, or when the audio device is trying to send audio data to the application more quickly than it can handle it. (Remember when Lucy and Ethel were working at the chocolate factory and the machine sped up to the point where they were dropping chocolates all over the place? Pretend the chocolates were samples, Lucy and Ethel were the audio application, and the chocolate machine is the audio device/driver, and you'll have a pretty good visualization of how this works.)
Typically, latency is not a problem if you're simply playing back existing audio (you might experience a very slight delay between pressing PLAY and when audio is heard through your speakers) or recording to disk without monitoring existing audio tracks since precise timing is not crucial in these conditions. However, when trying to play along with a drum track, or sing a harmony to an existing track, or overdub narration to a video, latency becomes a factor since our ears are far more sensitive to timing issues than our other senses.   If a bass guitar track is not precisely aligned with the drums, it quickly sounds sloppy. Therefore, we need to attempt to reduce latency as much as possible for these situations. If we simply set our Buffer Size parameter as low as it will go, we're likely to experience dropouts - especially if we have some tracks configured with audio effects which require additional processing and contribute their own latency to the chain. Dropouts are annoying but not destructive during playback, but if dropouts occur on the recording stream, it means you're losing data and your recording will never sound right - the data is simply lost.   Obviously, this is not good.
Latency under 40ms is generally considered within the range of reasonable for recording. Some folks can hear even this and it affects their ability to play, but most people find this unnoticeable or tolerable. We can calculate our approximate desired buffer size with this formula:
(Sample per second / 1000) * Desired Latency
So, if we are recording at 44,100 Hz and we are aiming for 20ms latency:   44100 / 1000 * 20 = 882 samples. Most audio devices do not allow arbitrary buffer sizes but offer an array of choices, so we would select the closest option. The device I'm using right now offers 512 and 1024 samples as the closest available buffer sizes, so I would select 512 first and see how this performs. If my session has a lot of tracks and/or several effects, I might need to bump this up to 1024 if I experience dropouts.
Now that we hopefully have a pretty firm understanding of what constitutes latency and under what circumstances it is undesirable, let's take a look at how we can reduce it for our needs. You may find that you continue to experience dropouts at a buffer size of 1024 but that raising it to larger options introduces too much latency for your needs. So we need to determine what we can do to reduce our overhead in order to have quality playback and recording at this buffer size.
Effects: A common cause of playback latency is the use of effects. As your audio stream passes through an effect, it takes time for the computer to perform the calculations to modify that signal. Each effect in a chain introduces its own amount of latency before the chunk of audio even reaches the point where the audio application passes it to the audio device and starts to fill up the buffer. Audition and other DAWs attempt to address this through "latency compensation" routines which introduce a bit more latency when you first press play as they process several seconds of audio ahead of time before beginning to stream those chunks to the audio driver. In some cases, however, the effects may be so intensive that the CPU simply isn't processing the math fast enough.   With Audition, you can "freeze" or pre-render these tracks by clicking the small lightning bolt button visible in the Effects Rack with that track selected. This performs a background render of that track, which automatically updates if you make any changes to the track or effect parameters, so that instead of calculating all those changes on-the-fly, it simply needs to stream back a plain old audio file which requires much fewer system resources. You may also choose to disable certain effects, or temporarily replace them with alternatives which may not sound exactly like what you want for your final mix, but which adequately simulate the desired effect for the purpose of recording.   (You might replace the CPU-intensive Full Reverb effect with the lightweight Studio Reverb effect, for example. Full Reverb effect is mathematically far more accurate and realistic, but Studio Reverb can provide that quick "body" you might want when monitoring vocals, for example.) You can also just disable the effects for a track or clip while recording, and turn them on later.
Device and Driver Options: Different devices may have wildly different performance at the same buffer size and with the same session. Audio devices designed primarily for gaming are less likely to perform well at low buffer sizes as those designed for music production, for example. Even if the hardware performs the same, the driver mode may be a source of latency. ASIO is almost always faster than MME, though many device manufacturers do not supply an ASIO driver. The use of third-party, device-agnostic drivers, such as ASIO4ALL (www.asio4all.com) allow you to wrap an MME-only device inside a faux-ASIO shell. The audio application believes it's speaking to an ASIO driver, and ASIO4ALL has been streamlined to work more quickly with the MME device, or even to allow you to use different inputs and outputs on separate devices which ASIO would otherwise prevent.
We also now see more USB microphone devices which are input-only audio devices that generally use a generic Windows driver and, with a few exceptions, rarely offer native ASIO support. USB microphones generally require a higher buffer size as they are primarily designed for recording in cases where monitoring is unimportant. When attempting to record via a USB microphone and monitor via a separate audio device, you're more likely to run into issues where the two devices are not synchronized or drift apart after some time. (The ugly secret of many device manufacturers is that they rarely operate at EXACTLY the sample rate specified. The difference between 44,100 and 44,118 Hz is negligible when listening to audio, but when trying to precisely synchronize to a track recorded AT 44,100, the difference adds up over time and what sounded in sync for the first minute will be wildly off-beat several minutes later.) You are almost always going to have better sync and performance with a standard microphone connected to the same device you're using for playback, and for serious recording, this is the best practice. If USB microphones are your only option, then I would recommend making certain you purchase a high-quality one and have an equally high-quality playback device. Attempt to match the buffer sizes and sample rates as closely as possible, and consider using a higher buffer size and correcting the latency post-recording. (One method of doing this is to have a click or clap at the beginning of your session and make sure this is recorded by your USB microphone. After you finish your recording, you can visually line up the click in the recorded track with the click in the original track by moving your clip backwards in the timeline. This is not the most efficient method, but this alignment is the reason you see the clapboards in behind-the-scenes filmmaking footage.)
Other Hardware: Other hardware in your computer plays a role in the ability to feed or store audio data quickly. CPUs are so fast, and with multiple cores, capable of spreading the load so often the bottleneck for good performance - especially at high sample rates - tends to be your hard drive or storage media. It is highly recommended that you configure your temporary files location, and session/recording location, to a physical drive that is NOT the same as you have your operating system installed. Audition and other DAWs have absolutely no control over what Windows or OS X may decide to do at any given time and if your antivirus software or system file indexer decides it's time to start churning away at your hard drive at the same time that you're recording your magnum opus, you raise the likelihood of losing some of that performance. (In fact, it's a good idea to disable all non-essential applications and internet connections while recording to reduce the likelihood of external interference.) If you're going to be recording multiple tracks at once, it's a good idea to purchase the fastest hard drive your budget allows. Most cheap drives spin around 5400 rpm, which is fine for general use cases but does not allow for the fast read, write, and seek operations the drive needs to do when recording and playing back from multiple files simultaneously. 7200 RPM drives perform much better, and even faster options are available. While fragmentation is less of a problem on OS X systems, you'll want to frequently defragment your drive on Windows frequently - this process realigns all the blocks of your files so they're grouped together. As you write and delete files, pieces of each tend to get placed in the first location that has room. This ends up creating lots of gaps or splitting files up all over the disk. The act of reading or writing to these spread out areas cause the operation to take significantly longer than it needs to and can contribute to glitches in playback or loss of data when recording.

There is one point in the above that needed a little clarification, relating to USB mics:

If you are going to spend that much, then you'd be better off putting a little more money into an external device with a proper mic pre, and a little less money by not bothering with a USB mic at all, and just getting a 'normal' condensor mic. It's true to say that over the years, the USB mic class of recording device has caused more trouble than any other, regardless.
You should also be aware that if you find a USB mic offering ASIO support, then unless it's got a headphone socket on it as well then you aren't going to be able to monitor what you record if you use it in its native ASIO mode. This is because your computer can only cope with one ASIO device in the system - that's all the spec allows. What you can do with most ASIO hardware though is share multiple streams (if the device has multiple inputs and outputs) between different software.
Seriously, USB mics are more trouble than they're worth.

External Usb Audio Card Popping and Cracking sound with Satellite L500

Greetings,
My name is Boyan and I am from Bulgaria and about an year ago I've bought a satellite laptop from the l500 series ( i can not state which exactly is the model at the moment because my computer is not currently with me and on my user manual the only thing which is stated is that it is for L500/L505/ L500D / L505D . But by memory I think it was the Satellite L500D-ST5506 which is currently not at my dispossal because I gave it for repair for the same problem which I will state down below)
The problem with my laptop is that when I plug a Usb Audio card in my laptop I have a cracking sound when live sound is played trough the speakers/headphones from the external card. I've tried numerous audio cards and speakers/headpohnes which work perfectly fine with other computer, including laptops but the same problem keeps on showing up in the headphones/speakers of my laptop when I am using an external audio card to connect them to the laptop.
The problem is prominent only when the sound signal passes trough an external audio card and it is very annyoing since I use my laptop to create music and i've bought an expenssive audio card and speakers which can not be used with the laptop. I've tried 3 models of audio cards:
M-Audio Fast Track Pro
Behringer uca 222
and a simple external 3d sound usb audio card and the problem still appears.
At first I thought that the problem should be software and I should install new drivers although windows 7 automaticaly recognizes and intalls the drivers for the devices and I have sound in them (but with cracks and popps) so i tried using the official drivers sold to me with the audio cards but with no luck: The problem was still there. I tried finding new drivers of the audio cards on the official distributors websited and i've downloaded them but the problem was still there. Then i tried to delete every audio driver on my computer and just use the external audio card for sound but this dint help eighter. I've updated my drivers for my build-in audio card as well but again - no luck.
After that.the frist thing I did when (2 weeks after i bought the laptop) was to contact the store from which i bought my audio card and they stated that the problem may be eighter latency or high voltage from the laptop so they adviced me to try to lower the latency from the settings or to try and see if the problem remains if my laptop is only running on battery. I've tried both things and they didn't help. The audio cards worked without a problem on every other computer I've tried them on except mine. So they said to me that the problem couldnt possibly be from the audio cards .
What I did next was I gave my laptop to the official distributor of toshiba in my country so they can fix my problem. What they said to me was that the problem is caused from the version of windows which was pre-installed on my laptop and that it wasnt compitable with the audio cards (which was bizzar sounding because I've tried them on the same windows and they've worked, just on other computers). So I got back my laptop and changed my operating sistem from Windows 7 Home Premium 64bit to Windows 7 Ultimate Edition 64bit to Windows 7 Ultimate Edition 32bit and on all of those versions the problem was there: whenever I activate a Usb Audio Card and audio signal passes trough it I heard cracks and popps. I even tried isntalling Windows XP but the laptop wants spesific SATA drivers for the installation of Windows XP which although i did find - they didnt help me install XP and I didn't want to go in to the BIOS of the computer to try to put a new one and so on because I am not so sure about that and I could lose my warranty so I said to the official repair store for Toshiba in my town to put XP on my computer to fix the problem but they can't because they are not liscened to operate with software which doesn't have a recipt for its purchase ( which i didnt because i bought my windows xp long ago and i've lost the recipt)
I gave it for repair for the second time telling them that the change of my operating system did not solve my problem and what they did was they changed the whole motherboard on my computer, stating that the build in realtek audio device on my computer is not good enough to support an usb audio card or it maybe broken and they have to change the whole motherboard because the build in card is glued to it, so they did that but my problem wasn't solved. They told me that although I am using and external usb audio card the signal still passes trough my internal one and I have to disable it so i tried disabling it trough the control panel but this did not solve the problem and i do not have an option from BIOS to disable my build-in audio card. Another thing which I thought maybe causing the problem is that the two audio cards aren't working on the same bit rate and Hertz so I set both cards to 16 bit 48000hz DVD Quality (Also tried other options on the 3 cards i have) but...the same thing happend.
They told me that this is just my luck and that the build in audio card doesn't support this external audio cards and I should had been more careful when choosing my laptop at first.
I couldn't accept this awnser for several reasons:
1) This audio cards work on lower version of windows and are supported by much older models of Realtek and much older computers (one of them was bought 2000!!!!! and my laptop is from 2010!!)
2) The guys who were fixing the problem apperantley didn't go in so deep in to my problem because they didn't know what actually the problem was they just knew that there is a problem with the audio card and the computer interacting with eachother, they didnt know that there is cracking during live play from the external audio card.
3) I can not accept the fact that Toshiba is manufacturing models with chipset audio cards which can not support a simple external Usb Audio Card. This is totally unacceptable for me and I truly hope this is not the case!
4)They didn't try my audiocards on an other laptop from the same series stating that they do not have one at their dispossal at the moment so I will go tomorrow to a local store and try the audio cards by my self on the same computer in the store.
What I did now was I gave back my laptop for repair asking for a statement of the problem in wrtting with all details of the problem so I can go to court or ask for a new laptop but I will be charged with some money because according to them there is no problem in the laptop and the problem is that my external audio cards arent compitable with the build in internal chipset audio card. If I give my laptop for repair and there is no hardware problem I will have to pay some money. I will do this but I am now mad, since this will not solve my problem and I am loosing time and money.
What I am asking here is, if you can not help me solve my problem and advice me what to do to fix it, please provide me the details of the chipset build in audiocard on my motherboard, so i can investigate if it is compitable with my external audio cards and contact the audio card dealers to ask them for their opinion. Or if you can tell me with what it is compitable with and with what not, it would be great. I personally think that this laptop should have no problems at all with running a simple external usb audio card but I am asking you, if you know something more about that.
If the problem is from the build in chipset then Toshiba is manufacturing (or at least selling) audiocards which aren't at a normal standart but sadly I cant do nothing about it except complain to Toshiba and never deal whith such productgs anymore. In the other case if this is not true, then my laptop has a problem which is different and I will have to go to court with the repair mans for not fixing my laptop or not giving a new one when I have warranty which will not be Toshiba's fault and It will in a way solve my problem.
I hope you understand how Important this is for me and I hope I resolve the problem as soon as possible.
P.S
I would like to state that I am well aware of the grammar mistakes I have made in the text below and I would like to ask for your apologies as I am not a native English language speaker.

hi i just like to say i had a similar fault though i would be surprised if it causing yours,but you never know,my fault was my laptop lid, [9 months old] it contains the mic ,and when the lid was in a certain angle crackles could be heard worse when i had my external sound card in, it was a faulty membrane [ lid to body] easily missed by engineer because it was the same angle all the time it happened,good luck, PS you English is very good

No audio after USB audio accessory is connected

I've discovered what I believe is a rather interesting (and rather serious) bug in the iPhone 2.0 software:
When an USB IAP accessory (such as a lot of newer car stereos) is connected and disconnected a couple of times the audio output from the iPhone will often stop working. Disconnecting the accessory or plugging/unplugging headphones does not fix the problem.
And I mean the audio completely dies: I get no audio from the phone, voicemail, ringtones, iPod, or system sounds from the speaker, headphones, or dock output.
It's like the audio drivers crash. Sometimes the audio will start working again after a long period of time (like if the phone has been sitting idle for hours while I'm at work) but usually I have to reboot to get it working. It seems when I can get audio to work again without a reboot, I get a new crashReporter log about mediaserverd the next time I sync.
The problem occurs when the phone is connected to an iPod accessory that uses the IAP audio-over-USB capability (I tried my Pioneer car stereo and a Kenwood stereo at Best Buy) It does not occur when connected to an accessory that only uses analog audio. I've seen it happen on my iPhone 3G and the original iPhone, so I know it's not a hardware problem.
I know for a fact the Pioneer and Kenwood units I tested are stated as having USB inputs compatible with the iPod Video, iPod Nano, iPod Classic, and iPod touch. (I can confirm the Pioneer does work fine with my old iPod Video.)
Multiple reviews have shown them to also work well with original iPhones running 1.1.4 and below (even if you do get the "not made for iPhone" warning)
However, both phones I tested are running 2.0. Which leads me to think this is a bad 2.0 bug.

Q100 audio drivers for Windows 7?

I recently purchased a Q100 (3014-1CU), and after an initial bootup to the factory installed Win XP, I installed Windows 7 (32-bit), via USB cdrom. That process went smooth and everything works except for the audio. Windows 7 detected audio as "High Definition Audio Device" and uses the generic microsoft provided driver (hdaudio.dll). Though the device itself seems detected correctly (there is no yellow exclamation point in device manager), the audio emitted contains crackling, static, and appears to be slightly off pitch. It is similar to a problem I had a long time ago (on different hardware) where the wrong bitrate was set for the card. So anyways, I've tried everything I can think of to get the audio working:
- Verified all physical connections are secure (Since the audio worked in my initial bootup to XP, this shouldn't be the issue)
- Swapped speakers and cables (same problem)
- Tweaked various audio settings: Tried all available bitrates, disable digital enhancements and pretty well every other driver-exposed setting was tweaked
- Tried other generic audio drivers that microsoft ships (Microsoft WDM Audio Drivers; another version of High Definition audio device). These drivers did not even initialize
- Tried to tweak BIOS settings (only thing in BIOS is to disable the onboard audio outright)
- Looked on lenovo's website for updated drivers: Nothing is available for Q100
- Looked on SIS website for updated drivers: Nothing is available for this chipset
- Did a PCI database lookup and found this to be a Realtek based device; installed the newest driver's found on www.realtek.com.tw (version R2.39). These drivers installed correctly, but did not fix the problem.
So at this point, I'm suspecting I'm going to need a lenovo or Sis driver to get this working. Can someone from lenovo point me to drivers for this device (even if they are XP drivers) or offer any suggestions?
Thanks

For anyone else who runs into this issue, I managed to "fix" the problem by installing an old version of the realtek driver (5898_PG281_VISTA_TurnOff_PullMode_Upd), found with a bunch of other debugging and hints on this thread: http://www.sevenforums.com/sound-audio/22369-realtek-windows-7-64rtm-crackle-static-popping.html
I'm still looking forward to seeing an official driver posted by Lenovo for this issue, since the old driver is out of date, removes some functionality and is unsigned

HP Slatebook 14 Android USB Audio

Hi,
Can someone tell me if my USB-DAC HRT Musicstreamer II+ would work with Hp Slatebook 14 Adnroid laptop 4.3 jelly bean? Both has type-A usb plugs and I can provide power to DAC from another source if this laptop can't provide it.
http://www.hirestech.com/product/?pid=128
Thank you for your answers.
Br. Jiri

Hey @HKI15 ,
Welcome to the HP forums.
I understand you're looking for information on compatibility with a USB sound card.
It has proved difficult to find detailed specifications for the device to really give you a direct answer. According to the information page it only lists Windows, Mac, and Linux using the Audio Class 1 drivers that are pre-installed in their operating systems.
This doesn't really mean that it won't work, but it might not work. For any USB device to work on the Android operating system it requires 2 things: The host device needs OTG support (which the Slatebooks do) and the software needs to support the hardware.This means you may not be able to use the USB audio playback option natively on the system, but should be able to find some apps on the Play Store that can do it.
My best answer I can give you is: Try it and see what happens!
Thanks.

USB Audio Interface Mystery

I have an HP Envy TouchSmart m7. Purchased it with Win 8 and upgraded to Win 8.1 update 1 (with August 2014 update).
No issues with the exception of a USB device. I normally have not used any USB devices - no USB keyboard, no USB printer, etc.. I have used a USB mouse once in a blue moon - but I do use a USB audio interface for my MIDI keyboard regularly.
It works fine until I connect a cable from any of the outputs to a mixer or amp. Within minutes, I hear a click and my audio driver stops responding as if the device rebooted - I'm assuming because of a USB power or data drop-out. I've replaced my audio interface, tried different power sources, different locations, all types of surge strips, modified power settings, replaced mixers, upgraded my BIOS, checked Windows updates, been talking with the maker of my audio interface (who even sent me custom drivers) and talking with the makers of my music software - all of them are at wits end saying to simply use another computer.
Help - help and help! I cannot perform with my audio interface not working. I have to connect it in order to hear sound. Everything seems to point to hardware on my laptop. Any ideas or fixes for this laptop?
Thanks,
Chris

Hello,
AS I stated earlier - the maker of the problematic device (which has a solid reputation) has sent me new drivers that aren't widely available although the drivers seemed and still seem solid and I've never mentioned nor had an issue with latency. Although you said I didn't mention updating any of the drivers, I may have inferred it by saying I installed any and all Windows updates which included drivers.
I have worked with PC's for 20 years, building, supporting, programming, etc.. I have seen a plethora of problems that run the gamut of easy to very complex and even to unexplainable - which I usually don't accept.. lol. This laptop runs smooth and I've tuned it up as my main music machine but this issue runs pretty deep and on the surface I can't see a driver issue, no latency issues and no updates pending for anything. What has my curiousity and perhaps I've not been as detailed as I shoud have been but that this problem does NOT occur and may never have occurred if I only used headphones. It only happens when a cable - any cable - is plugged up from my audio device to another device like a mixer or amp.
That's why I explored grouding issues, electrical possibilities etc. This may be a complex combination of several factors. Maybe a USB issue, along with a driver and/or even a deep OS issue along with grounding?
Thanks for the link to Windows 8 Tuning Tips for Audio processing but honestly, I had already performed these modifications way before I found that article and read it even before you posted the link. But thanks for being thorough.
I'd actually be happy if I had to address some clicking or popping - but a complete failure when only cables are connected? What can I do in the cabling to prevent surges? I hate to purchase expensive equipment to troubleshoot this, find a surge issue only to have to purchase another laptop, audio interface or something. Throwing more money at it for only troubleshooting purposes doesn't seem pleasant to me.
I have blue screen logs, memory dump files, etc which have been handed over to Focusrite and still nothing. I'd like to install Win 10 on it to see if this reoccurs or drop back to Win 7. I don't know what to do,,, my first audio interface device to fulfill my dreams of playing live performances and I hit this.. Agh!!!
Frustrated but still willing to troubleshoot,
Thanks,
Chris
