How do I Report Problems Regarding Devices Not Working Properly?

And how you know , how you are sure, that this is a problem related to hardware and not alsa driver ?

This problem is very common (sound produced from both devices same time) and if you want to fill a bug make it for alsa package.

However this problem can be fixed (not exactly fixed , but a workaround) with an option in alsa-base.conf file.

FIRST

Open alsamixer from terminal

alsamixer

and check if auto-mute is enabled.

If it is , then copy-paste this command to your terminal

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && bash alsa-info.sh --upload

and provide here the informations (OR the link).

Thanks

I can see how I wasn't clear.

This issue isn't that sound is coming out of both devices; it is that once I select "Digital Output (S/PDIF) USB Device" (under the "Output" tab of the "Sound" preferences dialog), the sound continues to be played through my internal speakers AND no sound comes out of the ArtDio NB-005B USB Speakers (for which my selection specifies).

Again, this behavior started after upgrading to Ubuntu 12.10 beta 2, but worked correctly in 12.04.

When I run alsamixer, it says

│ Card: USB Device 0x46d:0x821 F1: Help │
│ Chip: USB Mixer F2: System information │
│ View: F3:[Playback] F4: Capture F5: All F6: Select sound card │
│ Item: Esc: Exit │
│ │
│ │
│ │
│ This sound device does not have any playback controls.

----------------------------------------------------------------
Actually, that's probably not the right device. It is this one, and it is not muted:

│ Card: USB Audio Device F1: Help │

Maybe its time to convert this question to a bug ?

Search first if a similar (or the same) bug exists and if not you can
give it a shot. If exits then just add your comments there , and click
on "Yes it affects me" button.

Developers will request for additional info and they will search your
problem.

If you don't know how to report bugs , read here first:
https://help.ubuntu.com/community/ReportingBugs

If no one else has an idea to solve your problem here, you can follow my
advise and mark this question as solved.
