Hello *,
sorry for posting this to devel and users, but i think this could be
interesting for both. Plz. send replies in cc to my mail address because
i am not on list.
I am a proud owner of this flagship mainboard with a nvdidia mcp55
hdaudio sound card. The chip is identified by alsa as a AD1988A rev.2
(dmesg, lspci -v, lspci -nv output below):
The problem is that if i activate only front in kmix all is fine.
Speaker-Test works as expected. If i activate lfe/center then the sound
is messed up and he plays front-left/front-rigt through center and lfe.
I have played around with differend model settings: 6jack etc. no model
worked.
PLZ: help or if i can help you with my hardware i will do so...i have a
little linux experience and could compile alsa drivers in debugging mode
to play around with this things and hopefully find the right
configuration for this mainboard.
thanks in advance
cheers,
daniel
