Comment 49 for bug 345627

For me the problem is similar:
When playing the "new mail" sound in thunderdbird it often jitters and cracks.
When watching a video with VLC this problem occurs often (jitter, crackling); the same video with Totem seems to be fine.
Songbird sometimes cracks, but there it doesn't seem to be that often.
