ECS K7VTA3: Mixer channels reversed

[walt <w41ter@gmail.com>]

Hi list,

I just replaced a mobo with an ECS K7VTA3 and I find that the
Headphones control is now controlling the master channel and the
Master control does nothing.

I tried 'modprobe via82xx ac97_quirk=hp_only' but that makes the
audio device unusable (although alsamixer still seems happy to set
the individual channels).  Any other quirks I should try?

Here is some hardware info:
