snd_hda and via codec: no sound or full volume

[David Demelier]

Hello,

A friend has a computer with a HDA VIA codec, he told me when he's 
trying to increase/decrease vol with mixer nothing happens : in fact 
only mixer vol 0 or mixer vol 1 change something. The values between 
1-100 are the same volume.

This is dmesg about snd_hda with verbose mode :

and /dev/sndstat:

FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA VIA VT1708S_0 PCM #0 Analog> (play/rec) default
pcm1: <HDA VIA VT1708S_0 PCM #1 Digital> (play)

What happens?

Cheers,
