I am unable to get audio from the HDMI port on the Radeon HD 4670 (RV730 GPU) to our new Sony LCD TV. The TV works fine, and plays audio over HDMI when the same PC is running WinXP. I haven't had a HDMI device to connect to before but sound from the onboard sound card was fine.
Running Fedora 10 (kernel 18.104.22.168) and using the open source radeonhd driver (ver. 1.2.5).
Although this box is an HTPC intended to run MythTV there is no HDMI audio from any applications. I followed the advice here http://www.mythtv.org/wiki?title=All...italAudioHowto
but to no avail.
Grateful for any suggestions...
