the ATI-IXP audio stuffs loaded
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..
Uh huh, and when running skype. ekiga, audacity, or anything else that
requires this full duplex operation, it doesn't effect this particular
phenom other than turning the overall volume down, and when you run it
back up to the audible level, its still doing it with as much enthusiasm
as when you turned it down for effects. It specifically is not related
to any gain control's settings.
