[Bug 1244501] Re: Regression: audio stopped working after upgrade to 13.10

 

Calidonia Hibernia, please do not mark this a duplicate of another bug
or vice versa. As well, if you have a belief it may be a duplicate,
please explain in full technical detail why this would be, with
offending commit.

Dima Ryazanov, could you please confirm this issue exists with the
latest development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
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 all the way at the bottom) 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-v3.12-rc7

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:
  Regression: audio stopped working after upgrade to 13.10

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After the upgrade, sound stopped working for me. The volume would
  always be set to 100% after booting, though I couldn't hear anything.

  I went to the audio settings, and discovered that the hardware profile
  was set to "Digital Stereo (HDMI) Output". Changing it to "Analog
  Stereo Output" fixed the problem.
