I have Asrock K7VT4A Pro motherboard with via VT8237 chipset. Sound is
great, I just can not control the volume. I know it is a known issue,
but maybe this information can help someone to resolve this problem. I
run FreeBSD 5.4-RELEASE-p6.
I applied a patch from
but still no luck.
After that dmesg shows:
dmesg | grep pcm
pcm0: <VIA VT8237> port 0xc400-0xc4ff irq 22 at device 17.5 on pci0
pcm0: <Unknown AC97 Codec (id = 0x434d4983)>
pcm0: <VIA DXS Enabled: DXS 4 / SGD 1 / REC 1>
FreeBSD Audio Driver (newpcm)
pcm0: <VIA VT8237> at io 0xc400 irq 22 kld snd_via8233 (5p/5s/1r/0v
channels duplex default)
Win driver says it is a CMI 9761A codec. If I boot from "live" FreeSBie
CD, 1.1 it is the same situation.
Thanks for your support, Ales.
