the ATIIXP in my MSI exhibits this same issue. essentially, if the 'PCM' level
is set to 100%, things are horribly overdriven. the solution is to set the
Master to 100%, and adjust volume with PCM, instead of vice versa. i guess
whether this is a hardware bug or a driver bug depends on if PCM is the last
point of software contact with the stream and master trims the levels after
that, or if PCM just does some multiplication on the bits before passing them
to the Master..
Distortion if all volumes are set to 100% is not necessarily a bug.
It's just the way some hardware works.

We understand that all too well, from doing that particular balanceing
act with the older SBLive cards, which could be run plumb out of digital
headroom without even trying.
