Title:
  [Lenovo Thinkpad T60, AD1981] stuttering audio after suspend/resume

Status in “linux” package in Ubuntu:
  Expired

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
