Zach,

Thought I'd save you the trouble of starting a new thread to ask me 
about HDMI audio.

Believe it or not, I'm using ALSA to PulseAudio 0.9.15.   I've also 
tried the MythTV patch for PulseAudio (5473).   (I did at one point 
sideline Pulse and use ALSA native, but I couldn't use my Bluetooth 
headset properly that way.)  I figure Myth has to support Pulse properly 
at some point, given that it's so integral to newer distributions.

Pulse let's me redirect the output to HDMI or analogue.... and I can 
even play it in stereo over my Bluetooth headphones.

However, it's not perfect.  With ALSA->Pulse, when I fast forward, I 
have about a 1-in-3 chance of not having any audio... so I might have to 
forward a little further on, or back up a bit until I get it again.  
Annoying, but I live with it in the hopes that someone will fix it one 
day  ;-)  Not sure it would be acceptable to my wife, but I haven't put 
my system into production yet.

PuleAudio direct I always loose sound after a fast/forward, pause, 
volume change, etc.... and there's no way to get it back short of 
starting the recording over again.   It looks like 5473 is seeing some 
attention, so I'm hopeful it will be the final solution.
