That's cool. I do have one slight problem with it though: When I turn 
down the Master mixer and up PCM it sounds badly overmodulated. I can 
keep PCM at about 75% and turn up master, and all is fine. Would it make 
sense to limit the PCM mixer to about 75% of its current limits, or how 
does that actually work in the hardware?
