Information on enabeling S/PDIF output for MythTV

References http://www.mythtv.org/wiki/index.php/DigitalSoundHowTo


ASOUNDRC

Note: this is for a nForce2 soundcard

Create a file in your home directory (~/.asoundrc)

pcm.nforce-hw {
   type hw
   card 0
}

pcm.!default {
#   type plug
#   slave.pcm "nforce"
   type hw
   card 0
   device 2
}

pcm.nforce {
   type dmix
   ipc_key 1234
   slave {
     pcm "hw:0,2"
     period_time 0
     period_size 1024
     buffer_size 32768
     rate 48000
   }
}

ctl.nforce-hw {
   type hw
   card 0
}

MythTV Settings

General
Audio Output Device: ALSA:default
Note: This option is not available from the pulldown, it must be typed in

[ ] Enable AC3 to SPDIF passthrough
Note: Only check this if your tunner is encoding in AC3

Mixer Device: ALSA:default
Note: This option is not available from the pulldown, it must be typed in


Xine Settings

If using Xine as your MythVideo and/or MythDVD video player you need to set the "Audio Arangement" to Pass Through under Audio Settings.


Other Notes

Try to start with a clean modprobe.conf file. Remove any lines related to the soundcard. Reboot Then as 'root' run:

/sbin/alsaconf

Let it add the necessary lines to /etc/modprobe.conf

alsaconf is part of the alsa-utils package
