[Bug 518863] [NEW] Audio fuzziness and sometimes total wash out

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.
