I assume you already check the Wiki 
http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound_with_AC3_and_SPDIF. 
Also, can you get it to work correctly with mplayer? MythTV is almost 
never the SOURCE of audio issues as it doesn't do much other then ship 
the stream to **wherever you tell it to go**.
