As is typical with a lot of these things, it seems as though the original reason I set out to use PulseAudio was based on false knowledge. Essentially: ALSA was able, and has been able, to do everything that I wanted, since … well, since before I setup this HTPC anyway. So I have done away with PulseAudio because it does not support DTS passthrough. I now have MythTV working properly. I am a very happy man. And it only took me … what, a few months! :)

Yeah, unfortunately PulseAudio doesn’t support AC3 or DTS passthrough, you’re right there. I only play music and watch TV through my system so stereo/PCM is good enough for me. I do wish that it properly supported AC3/DTS though, as it is severely lacking in this department versus Windows-based solutions which are capable of Dolby TrueHD and DTS HD Master Audio output!

I’m not as successful as you with this same issue. I get audio out via spdif but it’s only stereo. AC3 is not present in LiveTV (via HDHomerun) , or videos played via myth internal player or mplayer. Have seen other posts saying that PA doesn’t support AC3 or DTS passthru. I’ve haven’t been able to get AC3 since Mythbuntu 8.04 Others claim that removing PA and going back to ALSA works but not a good option now with 9.10 having a dependency with the desktop. Any ideas on workarounds? I only use spdif output and have tried all combinations of the audio setting in Myth so far.

Mythbuntu doesn’t have PulseAudio installed by default. There are two camps in this as with everything else FLOSS. Some people hate PA, some people love it. Anyway, MythTV now supports PulseAudio (in the latest trunk anyway), so everything’s jiving nicely now.

I’m surprised it wasn’t set up already. It should have been.
