that's confirmed, but can't be fixed. The hardware doesn't have a working 
master 
mute control and the driver avoid signal processing, so the control is just a 
placebo for some shitty software which expect a mute control to be there.

How about just set the master volume L and master volume R=0 when master volume 
mute 
is enabled.

and wehn unmute, return to original value of volume L and R.
