[LINUX] ALC662 - 5.1 output not working only downmx to stereo
#1
I have board with ALC662 sound card. Under XBMC Live I set - Analog output to default card without downmix. With ths configuration I receive error : "Couldn't iniciate audio device".
When I switch on stereo downmix, then I have stereo output working on this ALC662.
What I must change to get working 5.1 output via ALC662 ?

Thanks

I don't know why but many default configurations didn't work for me. My solution was to add the module option to the hda module.

/etc/modprobe.d/50-sound.conf:
options snd-hda-intel model=6stack-dig
#options snd-hda-intel model=3stack-6ch-dig
options snd slots=snd-hda-intel
# 5Dex.fj0ZQec8bb7:SBx00 Azalia (Intel HDA)
alias snd-card-0 snd-hda-intel

I also disabled pulse audio support in alsa.
