striscio, 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, as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux 996367

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) 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-3.14-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:
  [Lenovo Thinkpad T60, AD1981] stuttering audio after suspend/resume

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  If I start the computer the sound is ok. If then I suspend, after resume the sound in rhythmbox is clipped and distorted.
  If I log out and log in again the sound is back to normal.
  The strange thins is that if after suspend, when the sound is bad, I digit
  aplay /usr/share/sounds/alsa/Front_Center.wav
  the sound I hear is ok.
  If I play the same mp3 that in rhythmbox is clipping with
  mpg123 /my/favorite/song.mp3
  the sound is ok.
  If I play it with totem the sound is clipped
  If I play it with vlc the sound is clipped but (it seems) less than with totem and rhythmbox
  If I play it with clvc (command line dummy interface) the sound is ok.

  So it seems to me that this bug is somehow resource related. Heavier programs has wirst sound.
  Let me know if you  need more info or more tests.
  Thanks,

                 Gianpaolo
