F16 switched to using GRUB2 as the bootloader.  It uses a slightly

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.

No problem. :-)

Well looks like we have an answer the pulse audio daemon is not even running.chmod o+rw /dev/snd/*,

[root@Re02 ~]# pacmd info
No PulseAudio daemon running, or not running as session daemon.

I did some googling and tried the following :

#1. chmod o+rw /dev/snd/*

After logging out and logging back in the above command made no difference.

#2. authconfig --updateall --nostart
    rm -rf ~/.pulse

After logging out and logging back in the above also made no difference

After rebooting with the continued use of radeon.audio=1 on the command
line there was no difference.

Any additional ideas would certainly be appreciated.
