5.1-channel sound on 8-STABLE, snd_hda

[Mikle Krutov]

Hello, list!
I've got MSI mb 760GTM-P33 with ATI hd audio chip (pciconf shows '
device     = 'IXP SB600 High Definition Audio Controller'').
5.1 sound worked on 8.0-RELEASE (sound was on every channel, but i
could not change vol per-channel, only globally), and after updating
to -STABLE - i've got only 2 channels working.
Any ideas about that?
