I just got a Chaintech 7NJL6 motherboard and two things are not working. SATA
controller (works but only at 33 not 150) and AC'97 Sound. I knew the SATA
would probably not work but the AC'97 Sound I expected to. I'm using the
snd_ich.ko mod (the only one that works), and as soon as I log into KDE I get
a high pitch sound. You can hear the normal sounds as well but the high pitch
sound is very loud. I hope that someone else has ran into this before that
might be able to shed some light on this. And as always Thanks in advance.

Also here are the specs of the motherboard.
