[mythtv-users] Xine or Mplayer with files of any type (mpeg, avi etc) no sound

[Doug]

I am trying to get my media library to work with Xine or mplayer via :
mplayer -fs -ao alsa:mmap:noblock:device=hw=0.4 %s
or
xine -p %s
or
mplayer -fs %s

They all find my spdif port as 0,4 ( which works for mp3's and dvd's via 
myth and xine or mplayer as DVD player)
 but wont play a single file with audio,  but the video is fine?

How do I get the audio to play is the a command line issue?  an spdif 
passthrough issue?
