Try the setup I use. You can see a very long thread with solution of  
my own problems at http://www.gossamer-threads.com/lists/mythtv/users/ 
225991#225991

To save time here are the settings that worked for me:

Audio output device:  
ALSA:iec958:CARD=0,AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2
Passthrough output device: Default
Enable AC3 to SPDIF passthrough: [checked]
Enable DTS to SPDIF passthrough: [checked]
Aggressive Sound card Buffering: [not checked]
Use internal volume controls: [not checked]
