Hi
Just go into the audio settings in mythtv, and select the HDMI port.
This didn't work for me when upgrading to 0.24. I have an ION system as
well and ALSA reports 4 devices on the Nvidia audio card. I had to enter
ALSA:plughw:1,7 to get digital audio out of myth and into my receiver.
Anything else results in silence. I thought maybe that the HAD Intel card
was getting in the way but removing that had no effect. I get no audio on
hw:1,3 which I'm guessing is what myth is trying to use. I only see NVIDIA
HDMI in the list of sound devices after scanning and device 3 is the first
one that shows up in alsamixer. Device 7 is the ones that I need it to use.
I was planning on investigating it more to see what info the "scan" was
getting but have not had time to dig into it yet.
Below is the output from aplay:
