I have gotten a little further and now know my issue is somehow related to
mythtv. I have exported my backend recordings directory and have mounted it
on my frontend via nfs. This allowed my to open one of the .mpg files with
mplayer and it played on the TV with audio through the hdmi cable.

MythTV however, does not give me audio from live TV or recordings..
