Help! Onboard Optical Out on P5N7A-VM?? - vostok4 - 2009-07-29
Hi everyone!
I have read through countless posts on how to get HDMI audio working on a P5N7A, but I have not found many people detailing the process for optical out (trying to go to my receiver).
I have not had any luck really trying to get it going
I have done the following:
added "options snd-hda-intel model=6stack-dig" to /etc/modprobe.d/alsa-base.conf
Installed the 1.0.20 alsa driver (as reported by alsa-info.sh)
Unmuted IEC958 in alsamixer
Set default audio device and passthrough device to every combination of "default, iec958, hdmi" possible, in the xbmc config
I have the following in ~/.asoundrc:
Code:
pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0660
slave {
pcm "hw:0,3"
rate 48000
channels 2
format S32_LE
period_time 0
period_size 1024
buffer_time 0
buffer_size 4096
}
}
pcm.!default {
type plug
slave.pcm "dmixer"
}I have tried VBIOS options of setting Digital Output to HDMI Audio or SPDIF Audio.
I haven't tried ONBOARD SPDIF as I don't have a header for it... does anyone have the magic code
I have NO audio whatsoever!

I've done this so many times on this board. After starting with mythbuntu as the base just did 2 things . Added the line above To the alsa-base.conf and unmuted things in alsamixer. That's it on the ubuntu side. I use optical. Your setup may be different though.

works fine for me on that board. This is the guide I followed:
