[clug] spdif output for MythTV

[Paul]

As far as mythtv playback is concerned I'm pretty sure that my SPDIF output is ok
I set the DTS passthru and found a 6 channel video which confirms 5.1 is output correctly.

Like you I just can't get speaker-test to work, so I don't know if thats normal or just 
meant to be for std PC speakers ie not SPDIF output to an AMP.

I have some 6 channel wav files and and having no luck using aplay to playback them other 
than stereo..

I think at this stage I'm ready to give up and hope this isn't the cause of my 
prebuffering problems, but since I've changed to the "SLIM" playback profile ,I've seen 
less problems with video/audio out of sync.. (the price of HDTV huh)

thanks
Paul
