sound: enforce MASTER volume mute during playbackstable/15
MASTER mute (vol.mute) works while audio is playing. However, if a
stream is stopped and restarted (PCMTRIG_STOP -> PCMTRIG_START), the
audio will resume even though the mixer shows the MASTER volume as
muted. Other streams that are already playing remain silent. New streams
may also start playing audio regardless of the MASTER mute state.
The volume feeder now considers the MASTER mute when determining whether
a channel should be muted. This ensures MASTER mute is consistently
enforced for all streams and removes the dependency on trigger-driven
state propagation.
Tested with Creative Labs CA0132 card.
