[Bug 518863] Re: Audio fuzziness and sometimes total wash out

** Description changed:

  Binary package hint: pulseaudio
  
  After upgrading to Karmic, my sound quality is quite poor.  Playing MP3s
  and Ogg files through RB sounds like someone has set my equalizer way
  too high, with high notes and loud parts fuzzing out.
  
  In addition, apparently randomly, my audio simply stops sounding like
  audio and just turns into varying pitches of total fuzziness/static.
  The static is still the music as I can recognize the beat (fuzzy/static
  bass).
  
  If I hover my mouse over the sound icon in the notification area and
  adjust the volume using my wheel, it adjusts it by 1% output.  If I tick
  through the % I can almost always find a particular % that lets the
  audio come through without the static noise.  It seems like 44% is a
  particularly lucky output %, as it seems to clear up most problems.
