M571 Internal Audio

[yegor at box.vsi.ru]

Hello.

I've got a problem with M571 motherboard integrated audio under 4.10-RELEASE.

When play .au, speakers produce some noise for a second.
When play .mp3, speakers are silent and kernel reports:

pcm0:play:0: play interrupt timeout, channel dead

$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <CMI8330> at io 0x530 irq 11 drq 0 bufsz 4096 (1p/1r/0v channels duplex)

As of hardware, Windows 2000 recognizes two devices, both work fine:

CM8330 SB16 Driver (WDM)
Port: 0240-024f
IRQ: 07
DMA: 03, 07

C-Media CM8330 Audio Driver (WDM)
Port: 0530-0537, 0388-038f
IRQ: 11
DMA: 00

FreeBSD finds only the latter with help of snd_mss.ko.

Any ideas about making one or both devices work?

Thanks in advance
