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?
