Public bug reported: Binary package hint: pulseaudio
There is a faint crackling noise during sound playback. Killing pulseaudio (killall pulseaudio) and restarting apps removes the crackling noise (which is why I suspect pulseaudio). The noise is independent of cpu or hd load. Explicitly selecting ALSA or other in sound preferences does not help. There is still a crackling noise as long as pulseaudio is alive. The crackling sounds pretty much like a broken speaker or overpowered amplifier which can not handle certain sounds such as high-pitch. The noise is clearly heard when pressing the "Test" button in sound preferences. The problem has been there since Ubuntu 8.04 and I'm now using 8.10.
