All I can suggest is going through the ICH sound docs. Intel write both
register descriptions and programmers guide for their h/w. You might also
look at the ALSA driver. I believe the speed problem most likely lies in the
AC97 resets.
I know I promised to look into this, but I've been struck by a shortage of
time lately and don't see the situation improving in the near future. I'm
very close to calling it a day with the commit bit.
