Wrong audio output after resuming from sleep

[Aimevous]

I have 2 sound output devices on my laptop - 1 built in (Sigmatel) and 1 USB sound output (C-Media USB).

I have nicely configured in the sound preferences to have all the sound coming out from the C-Media USB device and it works nicely until I send the computer to sleep.

Once it resumes, audio will instead come out from the Sigmatel output, even though all the options in Sound Preferences are set to C-Media USB.

At first I thought it was a program fault (happened first with VLC) and I filed a bug report with VLC. And I decided to switch to amaroK meanwhile. Then I sent the computer to sleep again and now amaroK only outputs to my Sigmatel device!

I ran Totem and sound nicely comes out from my C-Media USB device.

What went wrong here?

Thanks!
(Running Ubuntu 8.10 and latest versions of VLC and amaroK)

Hi Aimevous,

Please, if you are still having issues, test with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p alsa-base 292660

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

Please let us know your results.
