--- Begin Message ---Package: pulseaudio Version: 0.9.19-1 Severity: important After fiddling with pulseaudio for several days I have determined that it is clipping sound or at the very least introducing noise into the audio stream. I played a song via rhythmbox with sane volume defaults for pulseaudio and got the clipping. When I played the exact same song via alsa, I got no clipping and the audio quality was superb.
