running FreeBSD 6.2-p3 with a generic kernel and snd_atiixp gives me no sound
on the notebook speakers. With headphones it is barely noticeable. I've tried
setting all mixer variable to 100 with no avail.
raptor at hexe:~> pciconf -l | grep pcm
pcm0 at pci0:20:5: class=0x040100 card=0x01311462 chip=0x43701002 rev=0x01
raptor at hexe:~> dmesg | grep pcm
pcm0: <ATI IXP 400> mem 0xfbdfc800-0xfbdfc8ff irq 17 at device 20.5 on pci0
pcm0: <Avance Logic ALC655 AC97 Codec>
There is an ALSA patch which fixes some EAPD for the S270 by flipping bit 0
(?) in register 0x7a of the AC97 codec... whatever that means.
I've tried fiddling around in ac97.c and snd_atiixp.c, but since I don't know
what I'm exactly doing, I wasn't successful so far :)
Would anyone be so kind in helping me with this?
