That mainly refers to the video portion of the signal. I'm assuming
that works, given you didn't ask about that first. ;-)
While booted with "radeon.audio=1" set, please run "pacmd info" and
post the output. That dumps PulseAudio's state and may provide clues
as to why your HDMI audio is not working.
