AFAIK nvidia drivers 100.14.19 and 100.14.23 are the only set of drivers that support hdmi audio. If my understanding of the problem is right this has to do something with the way apple tv actually adds audio to the hdmi signal. I believe that is actually being performed by the SIL HDMI transmitter and not nvidia hardware. As a result when X starts nvidia driver in fact kills whatever HDMI audio is present. Probably the only reason nouveau drivers work as they dont support HDMI audio. Switching to nouveau really doesnt help as you loose quite a bit of functionality. I dont think nouveau supports dds images and 1080p24 output as of yet, which are important features for xbmc imho. I always found that the xbmc UI is not as fluid compared to nvidia drivers. I have tried to compile the 100.14.19 drivers on newer kernels and have failed. I would also love to find a solution to this problem with newer drivers, as this has limited me to be running ubuntu hardy.
