Dumb question - did you select HDMI as your default audio output, or
as the output for the program you are trying to play? Or did you
select the option to have audio go to both devices? On my system, it
defaulted to going just to the sound card.

One other thing - I remember having to set up a special loopback to
get an analog input to the sound card to go to the HDMI sound
output, but I can not remember how I did it right now. The audio
part of my monitor died, and I had to go back to a set of speakers
off the sound card. (Hardware problem - it does not work with the
analog input either.)
