Title:
  ALSA re-verb (severe buzzing/audio distortion.)  EG:  When playing
  Pidgin alerts/YouTube

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  Getting very glitchy sound with Pidgin alerts. The alert will sound
  off but then what I would describe as severe audio distortion or
  reverberation. The buzzing can last until there is another sound
  output.  Very annoying.  Can also come and go when on YouTube.  This
  is within both Xubuntu Maverick Meerkat & Xubuntu Lucid on IBM T21
  hardware.

  Moderator may want to close down duplicate bug #605556 as I wrongly
  filed under pulse audio.  Hopefully attached right info this time as
  of what package instructions on Ubuntu Wiki.

  Many thanks.
