Specs: Asus G73JH i7/720; ATI Mobility 5870

I have read through a lot of threads on getting HDMI sound to work and non of them have fixed my issue. Granted I am very new to Linux and know only the GUI aspect of what it does from finding similarities that Windows 7 has. I would like to become a Linux Power User and I figured this would be a good step to get started.

I was able to successfully install my graphics driver and it shows in use. I connect the HDMI to my HD TV and I get no sound. I don't care about auto switch for sound, that would be great but not necessary. I just want my sound to work through the HDMI.

What I have tried:

Changed

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" 

pact set-card-profile 0 output:hdmi-surround
Failure: no such entity

Sound Settings:

Right-click Sound indicator ? Sound Settings ? Output Tab, and set

Digital Output (S/PDIF) Built in Audio
Speakers Built in Audio 

I only get 2 settings. If I right-click the area below those 2 in the "play sound through" box, I get no "show hidden devices". I am also doing all this with the HDMI connected to eliminate any possibility for error.
