Default Re: Problems with audio over HDMI on Apple TV

I have disabled the EDID check using the xorg.conf option
    Option         "UseEDID" "FALSE"
This didn't help. HDMI audio still doesn't work. However I can now boot the AppleTV when the TV is turned off. There is more information on disabling EDID and forcing the nvidia driver to use a specific mode here:

Many people complained that nvidia driver sends fake HDMI audio even when no audio available over HDMI, so TV uses HDMI audio input instead of analog. So I think in some release NVidia has added some check to decide whether to mute HDMI audio.
