Have you also tried setting up the correct audio device in your MythTV setup?  From the main frontend menu, go to Setup - Audio Setup, and on the first page, there is a place to select the audio device.  Mine says something along the lines of “Alsa:HDMI” or something like that.  You can scan for the different audio devices present and then choose the correct one from the list.  Check each, then use the testing pages to test audio output.

I bet the verbiage I mentioned above is dependent upon which theme you are using, but it will be something like that.

Good luck.

Mike
