can you plug the eeepc directly to the receiver and test that DD/DTS work ?

If you are using a recent version of alsa (>= 1.0.25) and mythtv 0.26;
then the audio settings page will tell you which device to use. You
simply need to go through the list, and it will show you if it detects
a device and what it supports.

My guess is that you're running a more recent version of ALSA on that
eeePC, one that check the EDID sent by the TV. The TV is reporting as
not supporting DD/DTS and as such, myth doesn't attempt to send
DD/DTS.
Sometimes when that's the case, the order into which you start the
appliances is important: amp , followed by TV, then start the PC

Start mythfrontend with -v audio,playback
then go into the audio settings. exit (don't do anything, just enter / leave)

then go and play something.

Post the entire output of the log here.
