Muting Alsa

Description

I've noticed that ALSA, unlike OSS, doesn't completely mute the sound. It is still faintly audible when "muted". This patch fixes that by switching off the sound when the volume is zero. For joined controls it checks that all the channels have zero volume before switching off. The assumption of two channels and the relevant comment are copied from volumebase.cpp .

I'm running the latest revision of mythtv 0.20 from ATrpms.net (0.20.1.158)on Fedora Core 6 and the mute button doesn't completely mute the sound so is this patch for 0.20 or for 0.21.

(In [15777]) Fixes #2788. Actually mute ALSA output when volume on all audio channels is 0 using patch from David Matthews.

Without this change the volume is only turned down to a low level when we want it the sound to go away entirely.
