I am using Gentoo and MythTV and Nvidia, and I have not been able to get 
anything out of mplayer and aplay, except no device found.

That said, MythTV works fine, and plays DVD's and recorded TV, as well 
as CD's.

I first unmuted iec958 in alsamixer.

What I did in Myth is go to Setup-> General -> Audio, and in the Audio 
output device type in:
ALSA:iec958

It is not in the drop down menu!

Under this entry for the passthrough device, there was a drop down 
selection for:
ALSA:iec958 {AES0 0x02}

Then I selected the two check boxes underneath for passthrough in DTS 
and AC3.

VLC works when I select S/PDIF, but only for video files.  VLC pretends 
to play the OGG files that Myth rips from CD's, but no sound comes out.  
The same happens with MPlayer.

What I would really like is to get VLC or Adobe Flash to play flash 
files over digital audio.  To do that I believe I need to get pulseaudio 
to work, which currently crashes.

It would be nice if  someone had a very detailed guide with 
troubleshooting instructions for current ALSA with digital audio and 
pulseaudio, which I believe is required to play lower bit rate formats.
