Block by mute done with volume factor
Block by mute done with volume factor

There was a issue that also the volume module
in pulseaudio was touching the mute in stream
creation which ended up in race between the
modules. So let's leave the volume module alone
with mute and start using the volume factor as
server side internal mute.
