Loading 'snd_ich' kernel module dmesg states:
pcm0: <Intel ICH6 (82801FB)> port 0x1c00-0x1cff,0x18c0-0x18ff mem 0xb0040800-0xb00409ff,0xb0040400-0xb00404ff irq 17 at device 30.2 on pci0
pcm0: <Unknown AC97 Codec (id = 0x43585431)>
and there is no audio output.
Trying to add:
{ 0x43585431, 0x00, 0, "CX20468-31", 0 },
to
/usr/src/sys/dev/sound/pcm/ac97.c
albino# kldload snd_ich gives
pcm0: <Intel ICH6 (82801FB)> port 0x1c00-0x1cff,0x18c0-0x18ff mem 0xb0040800-0xb00409ff,0xb0040400-0xb00404ff irq 17 at device 30.2 on pci0
pcm0: <Conexant CX20468-31 AC97 Codec>
but still no sound!
Thanks in advance,
Dave
