I'm trying to nail down a strange behaviour. I have one "Master" and one "Speaker" (or "Headphone") volume control, each ranging from -48 dB to 0 dB. Whenever the sum of "Master" and "Speaker" is below -48 dB, the output mutes.

A known SigmaTel bug. Does your kernel already have these patches? http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=de8c85f7840e5e2962... http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=a74ccea51d4314632a...
