I don't know if this is one of the ATI cards that falls in the
unsupported category or not, but there are definitely ATI HDMI
cards out there with no HDMI audio support in current released kernels.

possibly includes your card (not sure though).

You may have to install the ATI proprietary drivers (if they'll
work with F16, which is also iffy :-).
