New snd_hda import and very low mixer volume

[Eugene Grosbein]

Hi!

I've just upgraded from 7.1-PRERELEASE to 7.1-STABLE via source upgrade
and divcovered that my sound stopped working. I was aware about
recent HDA driver update and tried to switch hw.snd.default_unit
back and forth but that did not help.

Finally I've realised that's just mixer values changed their meaning:
now I can't hear anything at levels 50:50 of both 'mixer pcm'
and 'mixer vol' and have to increase values significantly
to make sound: upto 85:85 of both.

Isn't it a bug?
I've Intel D975XBX motherboard with onboard Azalia HDA,
default unit is 0:

$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <HDA Sigmatel STAC9221D PCM #0 Analog> at cad 2 nid 1 on hdac0
[MPSAFE] (1p:2v/1r:1v channels duplex default)
pcm1: <HDA Sigmatel STAC9221D PCM #1 Digital> at cad 2 nid 1 on hdac0
[MPSAFE] (1p:1v/0r:0v channels)
