Beware Trinity CPUs need Quantal ?buntu 12.10 for HDMI sound to work. Built a A6 5400k sys. Tried many ?buntu 12.04LTS versions with ati12.10 but the kernel is too old for those devices (aplay -l no HDMI at all listed). It appears kernels 3.4 or higher are needed for HDMI sound, not an easy find for me. Xvba daily-tested works great on Xubuntu64 12.10 with fglrx from repo. One small note - Synch playback to display forces major under scan for 720p24 h.264. Likely the older 1080P Sony panel is the reason. Unchecked it is full screen. 720p60 h.264 plays full screen if enabled. No big deal just reporting it as solvable strange behavior.
