Kmixer shows intermittently USB audio mixer(It works,too!)

I am perplexed by the sudden appearance of the USB audio mixer option.
It isn't always present in KMIX.
It has a PCM output volume control
It has an input option but no input shown.
Does anyone else have the USB Audio option in KDE?

I have found a use for the USB mixer in KDE.
If it stays loaded in KDE KMixer I'll be satisfied.
The trick is to enable XMMS with a .wav selection. Click on the O option on the left side of the XMMS display: select.....preferences.
Select Output Plug-in ALSA.....
Select ...Configure....
Select under AUDIO DEVICE ...USB Audio (hw1,0)
Select Mixer Card ...1 and PCM
Click OK
This provided stereo audio from .wav files on the usb Soundwave Optical 5.1 device connected to a USB port on my system while using XMMS. This device has a stereo output jack and an optical port.
At the same time, another .wav file was possible simultaneously( even the same .wav file) on the PCI audio channel from the normal KDE mixer and PCI card using other multimedia devices(kaboodle, noatun).
I do not have any device for 5.1 surround which is optically provided by the soundwave device(probably not properly addressed for it in the system anyhow).
Maybe this will help someone with their USB audio connect?

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

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.

Unless you can find a way to stop XBMC from using your DAC, I would try hunting down the update which broke it and file a bug report with the appropriate project. https://wiki.archlinux.org/index.php/Do … g_Packages.

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.
Thanks for the help

USB Audio Interface not working anymore

I have a Presonus Audiobox USB Audio Interface. Worked perfectly until I updated to Mavericks, now I get a screeching noise when used and the sound switches to the built in Mac sound.
So then I reboot and it does it again. The Audio box doesnt have any software since its a plug and play. Any help?

Hi ketpiano!

USB-Audio does not work correct on T430/T530

Hi all!
I'm owner of a T430 and a T530. Both are new PCs where I have installed Windows XP. The reason for XP is that I own older software and hardware, which is not supported on Windows 7. But it works fine and I have no reason to change hard- and software as long it fulfills my requirements! And Windows XP runs fine and fast on the T430 and T530.
Only problem is an EgoSys USB Audio interdace U2A. It is possible to install and run it, but there is a problem in the communication between operating panel and the hardware. When I move the slider for the level, the level jumps instead a smooth increase of the level, which means not alle values of the slider are transferred to the hardware. There is a similar behaviour with checkboxes: there are states of the U2A which are indicaed with LEDs. When I change the checkbox, sometimes the LED changes, sometimes not. This errors happen very frequently but not reproducable.
I tried several settings in the BIOS, like disabling one CPU, hyperthreading, USB3 etc. I tried the U2a also on a fresh XP-intallation without other software, but all without success, the behaviour of the U2A is always the same!
I also tested with an ExpressCard with USB-port from LogiLink, but this card does not recognize the U2A at all.
Up to now I have used the U2A on many different PCs without problems. What might be the reason that it does not work on an ThinkPad? Up to now I was very satified with the U2A and I would not like to replace it!

GKap

Hello faith67baillie,
Welcome to the HP Forums!
I understand there is no sound from CDs or your Music folder. I will do my best to help! First, I require the following information, and clarification of the issue:

Satellite M40: USB Audio doesn't work properly in ACPI mode

Hi all,
I just bought a Satellite M40 laptop which purpose will be to be used as a mobile audio system.
For that, USB audio devices are a great solution.
Unfortunately, although it was working properly while recording (sound is perfect with all USB Audio compliant devices I could test), there's an issue in Playback as I got lots of clicks and pops.
After lots of tryings and google searches, I fixed the problem by switching from ACPI computer to Standard PC mode.
That's a workaround.
But this way, I don't know anymore what's my battery status, and my laptop do not shutdown automatically.
In fact, my laptop is no more managed as a laptop :(
I suspect a very serious issue in one of the Toshiba components management. Especially, I would not surprised to be told that power management leads to some regular short system freeze, and thus the 10ms USB audio buffers fall into underrun.
This would not bother me so much if I was not part of the technical support team of a company that is also launching some new USB audio products that will fail to work properly with laptops.
My question is :
Is there any driver / bios update that gets rid of this issue ?
If someone from the Toshiba technical support wants to handle this issue directly with me, I would be pleased to help him, as I'm concerned professionnaly and personnaly.
Thanks in advance.
[Edited by: admin]

Thanks for your help Jeffrey,
But
- I checked with several USB audio devices, from different providers. The issue is the same.
- I checked with several applications (Winamp, MediaPlayer, ...). Same issue.
- I checked these devices with different laptops (tried 3 different models) : I have NO PROBLEM.
- The USB devices I use do not need external power supply. I tried EDIROL UA-25 which works perfectly in any case, but not with my TOSHIBA M40.
- I agree that some application can disturb audio management. But in that case, I would like to know which one from the standard installation is the cause, so that I can fire it. It's anyway curious to see that switching from ACPI to Standard mode fixes the issue, as all applications are still there. I would say the applications are not the issue, then.
- All Microsoft updates have already been installed
- I think I tried everything that could be done by closing applications, changing power management modes, system cache, ...
- I have no other hardware device connected/installed (printer or whatever)
- RECORD works perfectly. So if some application layer was disturbing, I would bet it would bother in Play and Record as well.
CONCLUSION : Unless someone can prove it (and I'm ready for some testing), I still believe there's a harware/driver layer that is faulty in the Toshiba management.
And I don't need to contact the manufacturer, as I AM one of them :)
If you are part of the Toshiba support, let me know. Maybe we can investigate together.
FYI : I had to create a new user ID for this forum as it did not accept the one I created this morning anymore :(
Thanks anyway.

USB audio suddenly stops working

It's really weird. Regular audio output works fine, but if I plug in a USB audio device it will work for about a minute and then stop. I can reproduce this reliably with both a Griffin iMic and a C-Media USB audio widget. Once the device has stopped working, if I unplug it and plug it back in it wiil work for another minute or so and then stop again. This only started happening in the last week or so. Before that it was working fine for months. AFAIK I haven't changed anything. I haven't done any major software updates, and I'm not running any new applications.
Also, while it's not working, it's not off 100%. It seems to have something to do with the audio driver. If, for example, I do this at the terminal:
say hello world ; say hello world ; say hello world
I will hear "hello ... hello ... hello ..." (where the elipses indicate about a second of silence).
If I do:
say hello ; say hello ; say hello
then I just get little blips of sound.
Has anyone seen this problem before?

IPhone USB audio only sometimes works

I decided to plug my Logitech H760 headphones into the USB adapter for my iPhone 4s.
The music app works perfectly.
The phone app however, does not.
The microphone on the headset seems to be the input for the sound to a call, but the output is still through the iPhone's built in speaker.
I wish the output to be through the headphone speakers.
Thanks.

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.

USB Audio Codec

Compaq Pressario 5220, Windows Vista, 32 bits (approx. 3-4 years old)
I bought a USB gramophone record player with a USB connection. This does only operate with a USB Audio Codec which I am supposed to find under Control Panel, Sound, Record.
Alas!
Any ideas on where to find/acquire such a codec?
JoeyBr

I have a Pyle USB cassette tape deck that needs this codec also to work with Audacity.I'm out of luck with the USB connection and have to connect it via RCA plugs to miniplug into Line In.
I have come to the conclusion that this codec only worked on Macs that used PPC chips,not Intel Macs.Apple must have dropped it when switching to Intel.No where on the net can I find anything about this codec on newer mac OS's and newer intel Macs.
Judging from this user's comment below and others,they are working with OSX10.4 and PPC's like G3,G4 and G5.Also later versions of Mac OSX that had support for PPC's like the first Mac Pro.
In Audacity prefs, I selected:
"USB Audio CODEC" for both Input and playback.
Mac is a 533Ghz g4 (Digitial audio) running 10.4.11
It is plug into a USB port on back of machine.
Attached is a screenshot from Audacity and it shows the USB Audio Codec. I was pulling my hair out,wondering why I couldn't see it in my audio sound setup in OSX 10.6.8 on my black Macbook.I couldn't find it in my system anywhere.This attachment showing the codec installed MUST have been done on a PPC G3,4 or 5. Nowhere does it exist on Intel Macs.
Disregard the red circle.

Using Audio Mixer

Hi,
Is it possible to connect a USB Audio Mixer with 3 microphones and stream it through skype? That is the person on the other end would be hearing from the 3 microphones I would have connected to the mixer. Thanks

There have been some cases, where only Microphone input one would work with Skype, so not sure. Might be a good idea to do a search using the search engine of your choice using this:
Make Model of mixer Skype problem
This way you can see, if this is the case with this mixer, if someone else has posted somewhere about it not working.
About Me You can also use a IP Camera as your camera for Skype video Example Instructions

Where do I find USB Audio codec in OSX 10.6.8?

I need this for a Pyle USB tape deck (PT-659DU). Audacity is the only program that can be used with this deck and they show clearly how to use Audacity with USB PnP devices,as this deck is one.This screenshot shows what I need to do.(find the USB Audio codec,and get it to show in the Audio setup in Sound
Prefs.

My last post to myself is wrong.I received a response from Audacity with USB audio Codecs support for Mac OSX on intel Macs.

My only question is,was he using a Powermac G3,G4 or G5 PowerPC based computer to show the USB audio codec installed? Mac Intel with OSX does not have USB audio codec in it's sound codecs anymore,nor does it support this codec anymore for usb record recorders & Tape recorders.
From Audacity:
Sorry, but that is just not true:
https://developer.apple.com/library/mac/technotes/tn2274/_index.html .
It must be PPC only to work with Audacity.Ask any user with problems finding this codec to install and you will find they have an intel based Mac.
Please correct me if I am wrong.
Add to your list of unsupported Cassette players. Pyle PT-659DU. There will be other models similar to this one with the same issue.I had to go analog RCA to work properly with Audacity.
See: http://wiki.audacityteam.org/wiki/User:BillWharrie/OSX_and_USB_input_devices
Pyle devices most likely just use the Mac's USB audio class driver as above.
However if your device's manual says you need to install a special driver for
Mac, you should do that.
In many cases, it's as simple as replacing the USB cable.
