I know some cards had to have the bios set to on or off or something
to allow the OS to see the thing.  I think I mention that in the
HowTo.  Restart and go into the bios and see what sound options there
are.  If I remember correctly, you have to turn SPDIF off to get HDMI
to go on, or something strange and counter intuitive like that.

I don't have HDMI so am not really that much help.  I was just happy
to solve the SPDIF problem.
