[regression] rhythmbox clicking in mp3 playback

Binary package hint: rhythmbox

1. Import a folder of MP3s.
2. Double click one to play it, in rhythmbox.

I get distortion and clipping under rhythmbox on any high sounds. I don't remember this happening in Feisty. This does not happen in totem, xmms, or audacious under Gutsy.
