Jeremy, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

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

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder, but the one at the top) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc4

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  USB sound card gets pulseaudio and the kernel to fail

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: ubuntu-docs

  Hi everyone,

  I have two USB soundcards and this bug happens whatever the card.
  After a while into every single session, my USB soundcard stops
  reacting (no more sound, can't control the volume) and I get these
  errors :

  And then a bit later :

  I have to restart to get the sound back. Disconnecting the soundcard
  and replugging it doesn't help at all.

  I use Ubuntu 9.10 final and the 1:0.9.19-0ubuntu4 version of PulseAudio.
  Tell me if you need more info.

  Thanks.
