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.
