Help! Onboard Optical Out on P5N7A-VM??
#1
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 Eek

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 codeHuh 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.
