Hi!

I just installed FreeBSD 5.3 on a VIA KM400 based chipset motherboard. 
The audio is the VT8237 audio chipset.

No sound is produced!!!

#kldload snd_via8233.ko

#cat > /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <VIA VT8237> at io 0xeb00 irq 22 kld snd_via8233 (5p/1r/0v 
channels duplex default)

#dmesg | grep pcm
pcm0: [GIANT-LOCKED]
pcm0: <Unknown AC97 Codec (id = 0x56494170)>
pcm0: detached

I tried that hack with no luck:

Now can somebody help me?

Thanks!
