Soundsticks (USB Audio) Distortion w/High SPLs...

I have a pair of Harmon Kardon Soundsticks (I've had them for a long time, maybe 10 years) anyway, they have been working flawlessly on my 2006 vintage Mac Pro yet lately the audio distorts when playing it rather loud and with some demanding material...
So, does it sound like there is an issue with the MP or the Soundsticks?
Thanks,
Robert

I have been having similar problems with my (much less fancy) USB speakers, intermittently, since the 10.4.6 update (PowerBook). From another post I made elsewhere:
I have Altec-Lansing XT1 USB speakers. They're connected to the PowerBook via a USB KVM, to an ADC, to the speakers.
For the last week or so (it started soon after 10.4.6 upgrade), an odd temporary sound distortion has been occurring. As the original poster mentioned, it sounds for the life of me as if the speakers are blown.
For anywhere from a few moments (several seconds) or longer, the sound output will become distorted in this way. Then, often of its own accord, things will go back to normal. If I want to get them back to normal more quickly, I can mute and unmute (I use a Logitech keyboard with a mute button, or sometimes I hit the Griffin Powermate which defaults to mute, and occasionally I even hit the sound control on the menu bar). When it's unmuted, it comes back undistorted.
Hence, this phenomenon seems to me to likely be software-related.
I almost always use the PowerBook closed and hooked up to an ACD. Lest you think this is particular to this set up: I have another identical ACD & speakers at the office (indeed, even the same keyboard), with the main difference being the lack of the USB KVM switch being left out. The problem happens there as well.
I welcome any thoughts.
Thanks,
Doug

USB Audio distorts when using Stanton T90

I have a Stanton T90 USB turntable that works ok with a PC.
However when used on my Mini Mac after a short time the audio starts distorting.
It seems to be application independent and in the logs I have seen:
Oct 30 23:22:01 Macintosh kernel[0]: WARNING: AppleUSBAudio has detected that a connected USB audio device is sending too much audio data.
Oct 30 23:22:01 Macintosh kernel[0]: WARNING: This USB audio device may not function properly. Please notify the device manufacturer.
Has anyone any ideas how to solve this?
Yours
Leon.

Hello thanks for the feedback.
I've 1Gb of RAM.
It happened when I only had my mouse and keyboard connected with nothing but Audacity running. However my mouse is connected via my Mac keyboard so I could try that on a separate port. From the error it appears that the USB port is not being read often enough.
Unfortunately it seems that Apple drivers can be just as prone to incompatibilities as Windows. You can find hundreds of articles about these issues with both Audio USB and Firewire devices.
My last step before throwing the turntable back at Stanton will be to reinstall my OS (Leopard) to see if an update has caused the problem.
Yours
Leon.

USB Audio Distortion After 10.4.6 Update

Have been using an Edirol UA-1D USB/Digital Audio interface with my Pismo for years. Optical connection for audio out to digital 8 track unit. Crystal clear signal. Painless operation. And NO drivers needed.
Updated from 10.4.5 to .6, and instantly I'm hearing a considerable and disturbing amount of distortion in the audio. It's not volume dependent or overmodulation (comes through even at low input levels). And it comes through iTunes, Reason, LIVE, etc... where it didn't before.
Since the Edirol unit uses built-in Core Audio, I'm baffled. I know Apple has been endlessly tweaking its OSX USB/Digital audio underpinnings, but I fear this latest tweak has knocked something out of alignment.
Any suggestions?
I zapped PRAM, "repaired" permissions, etc. No luck yet.
Would appreciate any insight.
Thanks in advance.

USB audio distortion

I'm having a problem with running a soundcard through my USB port. Seemingly randomly the audio signal is becoming disorted when coming out of one port. Changing the port does fix the problem, but now i have 2 USB ports that are unusable for connecting to my USB sound card device, and i fear that eventually all of them will go wrong
any ideas what this might be or how it can be fixed?

Itune song files won't play and my Soundsticks USB audio is not recognized on my G4 Cube running OS 10.4.11.

I have repaired permissions and reinstalled iTunes (ver. 8.2.1), but so far that has not helped.

If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

Best way to record high SPL audio?

I need a simple way to record higher SPL band rehearsals. I don't need studio quality or multi tracking. Just an audio recording that clear and as un distorted as possible. I know the built in mics on Idevises are not really made for higher volume stuff. My band has changed some of the structures of cover songs we are doing so practicing to the original artists studio recording does more harm then good. I just want to be able to record us rehearsing so I can practice to it at home. And get the changes and structure down before we play out live later this month.
I have quite a few idevices but the more modern choices at my disposal are: iPhone 5, iPhone 4, iPad (3rd gen) ipod (4th gen)
What device, app and hardware will healed best results. I've been told the mic on the earbuds have a better frequency response then the built in mic. So is it better to use that? And what app is good simple and effective at auto controlling the mic's sensitivity to reduce distortion.
Also I am the drummer and acoustically seated, in About the worst position for quality. So rather then have the idevice behind my kit where I can control it. I would need something I could place across the room and just record an hour or two.
Thanks.

Here's one solution that I use for vocal narration.
I have a Shure PG58 with a XLR to 1/4" connection, to which I added a 3.5mm adaptor. The mic was about $60, the adapter was $4.
(Edit: I've just noticed that Griffin makes an XLR to 3.5mm cable, which would eliminate the adaptor.)
You can't connect a mic directly to the line input of your PowerMac, because the level will be too low, but you can either use a mic pre-amp or mixer (if you already have these), otherwise, you can use a Griffin iMic (which is what I use) to convert the audio to USB, which gives you a decent level.

Distorted recording with QuickTime 7 using USB Audio CODEC

I am running Mac OS X Tiger 10.4.8 with all the latest update from Software Update which includes QuickTime 7.1.3.
I am using QuickTime Broadcaster to stream back to itself (loopback) and record to disk at the same time. The input audio device is set to USB Audio CODEC (the default driver that comes with Mac OS X Tiger, and I am using an Alesis MultiMix 16USB mixer on a PowerMac Dual Core G5). I am using MPEG-4 Audio compression (no Video) of 16-bit, 44.1kHz and 128kbps (stereo).
The problem is that sometimes I get recordings (ranging from 1.5 hours to 2.75hours long) with distortion. Here is a short 20-second audio clip with distortion-free audio for about 6 seconds and then distortion sets in:
http://www.netmedia.com.sg/files/SampleDistortion20s.mov
Whether it overlays on top of the original audio or replaces it, I cannot tell, but the transition is instant and smooth with no audible clicks or pops. The distortion can come in and go randomly. For example, I had one recording with distortion coming in at about 2 minutes plus and it remained until about 2hr10min when the distortion went away. Sometimes it didn't go away; other times it came in about an hour later. I also had once where the distortion last only for about 6 minutes somewhere in the middle of a 2.25 hours recording...all in all, it occurs at random. And I do get distortion-free recordings.
This problem also occurs on an iMac G5 with a Alesis MultiMix 12USB mixer, and in another Vara Software's Videocue PRO software which uses QuickTime for recording and playback. QuickTime 7.0.x and all versions of 7.1 also had this problem.
Because of this problem, I may need to use a convoluted method to stream and record to disk via QuickTime. By the way, I also tried streaming to another local subnet IP address just as a troubleshooting without success.

I too am having distortion problem (Sorry no solution here).
Using OS 10.4.8, QT7.1.3, & Adobe Premiere 6.5 on a G4.
After I down loaded QT 7.1.3, my problems started. Is this when your problems started too?
Audio is in "slow motion" sound when editing. On rare occations, it sounds correct for 10 sec or so but sync is out and eventually reverts to "slow motion" sound. Even more bazar, when viewing a clip in a thumbnail preview, it works fine. So I know the orginal is good.
My contention is QT is causing this. All I want is my previous version of QT back. I think this might fix your problem too. Unfortunately, there is no reinstall that I can find that takes QT 7.1.3 off and puts QT 7.1.1or2. The reinstall QT 7.0.3 which is on the Apple website will not restall.
Looking for a reintall that will take QT 7.1.3 off, help anyone?

USB audio Interface distortion/static when sound is played.

My USB audio interface started sending out static/distortion to my speakers one day. It's more apparent when volume is very very low. To troubleshoot I switched to the other USB port and it worked fine for a month or so. Now the second USB port is creating static. I have reason to believe it's the computer not my interface as there was static on one usb port and none on the other. Now both ports create static. Is there something in my computer I can try reseting or should I look into getting a new interface?
Thank you in advance for any guidance with this.

13" MacBook (Late 2008) 2.4Ghz w/ OS X 10.6.6

No noise problems when the interface is plugged into other systems.. Only on the G5...
And I tried plugging it into all the different USB ports on the G5, the one in front and the two in the back... All with the same result.
Thank you for your reply.

Distorted recording with QuickTime using USB Audio CODEC

The problem is that I usually get recordings (ranging from 1.5 hours to 2.75hours long) with distortion. The distortion sounds like audio going through Logic Pro's BitCrusher plug-in, that is, audio recorded with less than 8-bit resolution but kept at 44.1kHz sample rate. Whether it overlays on top of the original audio or replaces it, I cannot tell, but the transition is instant and smooth with no audible clicks or pops. The distortion can come in and go randomly.

Seems like you've answered your own question as those are the two ways to do what you are trying to do. Using the key-switch will be less CPU intensive than using multiple instances of the plugin.

USB Mic Distortion

I recently bought a Samson G-Track USB microphone, to go with my new Macbook (running Leopard), but seem to get intermittent audio distortion when I record. I have been checking the record levels on the mic and garageband and it's not clipping. If anything the signal strength on the Garageband monitor seems low. I can sometimes record a signal ok and then with exactly the same setup next time it distorts. I have tried turning off all effects in case they are causing it. Looking at online discussion forums there seems to be a problem with the Apple USB driver (Audio Codec?).
Anyone else had this problem?

I've had a Snowball USB mic for about a year and it sometimes has problems like you describe (basically signal breakup that sounds like clipping, even though the input level is not too high).
I first used it with a G4 Powerbook, and found that the perfomance depended on which port I used. The differences were dramatic.
I'm now using a MacBook, and there is variability when I record my band from session to session. I'm getting the feeling it might have to do with how well the power is sent from the USB port to the mic. But I don't have a good diagnostic.
I plan to sit down and run some trials, and would suggest you do the same. Plug in the mic, do a quick test and listen, then disconnect/reconnect the mic and repeat the test (changing ports or not).
I read recently that USB power is "dirty" and maybe these mics are very sensitive. If anyone has more info, I'd like to hear it.

Recording into Audition 3.0 via Behringer UFO202 USB audio device

I am running Audition 3.0 on a PC with Windows 7 Home Premium. This may not be the proper place for this question, but I was not able to put it on the Adobe Audition 3.0 and earlier forum.
I am trying to record cassettes into Audition via a Behringer UFO202 USB device. I plug in the USB and my computer sees it and I can hear via the headphone output that it is playing. I go to the Windows Recording Mixer and it indicates that a USB audio device is working. However, I cannot get the sound into Audition. It doesn't show up when I record to the edit window or click on the meters to monitor.
I am also using a HT Omega Sound Card, but their support said that it shouldn't interfere.
Any help would be greatly appreciated.
thank you,
New Orleans Audition User

Unfortunately you cannot reduce the levels of audio on it's way into Audition. Audition just records whatever the audio interface sends it. If the levels are that high when recorded into Audition then it is likely that you could be overloading the input to the Behringer interface. You need to somehow reduce the level at source in the analogue domain. Once it is in the audio interface at too high a level then any distortion caused will be burnt into the digital audio file and you won't be able to get rid of it.

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

Noises on external USB audio interface (Yamaha MW12) with Snow Leopard

Hi there,
I got an issue with strong noises (kind of distortion) while playing all kind of music/sounds ( itunes/Reason/Cubase) via an external USB audio device (Yamaha MW12 mixer).
Some important facts:
+ This had not been from the very first beginning of changing to snow leopard
+ but never appeared on "leopard"
+ Yamaha mixer is still working fine with my MS-windows computer
+ latest Asio driver by Yamaha is not helping.
+ internal audio of my Mac Book Pro is working fine.
As this issue just appears 2 days before, without any change or installation on my system, I really wonder, what could be happen. As Yamaha mixer is still working fine with other computer, I expect some driver in MacOS to be the problem (as internal audio HW is working fine).
Does anybody else, know, what to do? (before I change back to MacOS 10.5)
Has anybody else have seen a similar issue?
Thanks for helping in advance.
Merry christmas,
Mat

Hi,
just one addon.
+ Changed USB ports on MacBook and it was fine on the second used.
+ Nevertheless, noise remains on the originaly used port
+ all other connected devices as mouse and midi interface are fully functional on both ports
It still looks like a driver issue. Nevertheless, could it be a hardware issue with the USB port in my MacBook then? Even if all other tried devices are functional?
cheers, Mat

Windows 7 x64 USB AUDIO DEVICE - Device Not Working - Mac Pro

I have a mac pro early 2009. I had vista x64 installed, everything was great. I had 2 audio devices under device manager, one was listed as HD (digital) and one device was listed as analog audio.
When I played games and wanted the external speakers (using the digital out connection) I had the HD (digital) audio device enabled.
When I played games and wanted to use a headphone/microphone combo, I had the analog audio device enabled.
Switching between the two was as easy as clicking the audio device icon and clicking on whichever device I wanted.
Now that I installed windows 7 x64, I have a HD (optical out) device in device manager and it works perfectly. Unfortunately, I also have another device listed called "USB Audio Device" and it shows a yellow exclamation mark next to it and it is NOT working properly.
I tried many suggestions on here, which included downloading the cirrus logic audio driver and picking different models, as well as trying the snow leopard install disk driver for cirrus logic, and even tried installing the realtek analog driver. The closest I got to getting anything to work was installing the realtek analog driver. It installed fine up to the point when windows said "this driver is not tested, do you wish to install it anyway?" and I click yes, but then it pauses for a few seconds and the same message comes up again and repeats in a endless loop until you say "no, do not install driver" and then it does a uninstall of the driver.
Has anyone else experienced this problem and if so were you able to fix it?
Thanks

You can ignore USB audio, you want RealTek HD Audio. There are or can be some of those yellow alerts that are safe to ignore. Buried somewhere in Apple Support BootCamp technotes.
You can use installer from Realtek or zip file in which case just uncompress and update the driver from inside Device Manager. Nice thing, you can rollback a driver if you want to, or totally uninstall and then reinstall.
