Public bug reported: Updated from 10.10 to 11.04. Never had a problem with sound before. When no app plays sound, there's a faint high pich humming. When an app is playing a sound, it is distorted, the distorsion doesn't change when I move the volume sliders. (the sound is higher/lower but with the same proportion of distorsion) When playing a mp3 using deadbeef the music seems normal even with the distorsion, on the other hand playing a sid music the sounds is really odd in addition to the distorsion. Flash video on chromium has the issue. KDE sound notifications too. Amarok as well.
