[mythtv-users] Turtle Beach Audio Advantage Spdif help.

[Gregg]

I have just installed Mythdora 10.21 as a frontend, and I am trying to
get The Turtle Beach Audioadvantage working with spdif.  When I select
ac3 pass through I get static.  I have looked at the groups, and
people suggest unmuting iec958 in alsamixer.  Unfortunately it does
not give me that option it only lists PCM.  Is there a way to enable
that option in alsa?  Should I create an .asoundrc file?  I heard
fedora didnt need it anymore.

Here is what I get with aplay -l :
**** List of PLAYBACK Hardware Devices ****
card 0: default [USB Sound Device        ], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I do not see digital in the list.  Shouldn't there be?

I also get this from cat/proc/asound/
  2:        : timer
  3:        : sequencer
  4: [ 0- 0]: digital audio playback
  5: [ 0]   : control


Grateful for any insight.
