Public bug reported: I am running Ubuntu 8.10 with all available updates on an ASRock K7S41GX mainboard with onboard sound. Sound is working, but muting or reducing volume on the master channel does not work. It always stays on the same high level. Furthermore changing the PCM volume (which works in general) to the lowest position causes some crackling noise. Raising the PCM control to any other level stops the crackling.
Expected results: muting and changing volume on the master channel works, no crackling on lowest volume for PCM channel.
