Hi all,
    I wanted to get some guidance and suggestions regarding the 
possibility of support for the Nvidia NForce2 APU. I use the AC97 chip 
under Alsa, but I realize at this time the Nforce2 APU is not supported 
under Alsa. However, I'm wondering if there was any possibility that I 
could somehow modify either the snd_intel8x0 module that the AC97 uses 
or the snd_via82xx module, since that's what the Nforce2 APU is 
recognised as, to use the APU and AC97 at the same time? As I have some 
extra time on my hands, I am willing to try indepth to get the Nvidia 
APU working under Alsa. If this simply isn't possible for one reason or 
another, please let me know. If it is possible but with considerable 
effort, please point me in the right direction. If you reply to this 
post from the alsa-devel list please "reply to all" as I'm not 
subscribed to that list. Below is the output of lspci that shows how 
each chip appears on my system:
