I just bought a new Asus A7V600 motherboard, which claims to have an
"ADI AD1980 SoundMAX 6-channel CODEC" and a VIA VT8237 southbridge.
Unfortunately, the sound does not seem to be supported. That's what I
get for buying newly-released hardware I guess.
Here is the appropriate portion of pciconf -l -v:
none5@pci0:17:5: class=0x040100 card=0x80b01043 chip=0x30591106 rev=0x60 hdr=0x00
vendor = 'VIA Technologies Inc'
device = 'VT8233/33A AC97 Enhanced Audio Controller'
class = multimedia
subclass = audio
I tried simply adding my chip revision to the probe routine in
dev/sound/pci/via8233.c (patch included below) with this result:
pcm0: <VIA VT8237> port 0xe000-0xe0ff irq 5 at device 17.5 on pci0
pcm0: <Analog Devices AD1980 AC97 Codec>
I was then able to play sound, but with an odd beeping noise.
If there's anyone out there who wants to try to get this working, I
will gratefully help in any way I can.
Thanks,
