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 SettingsOutput 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.

Have you tried with the fglrx closed source driver? Some cards that seems to work. –  hbdgaf Aug 25 '12 at 2:14

You will need to install the binary driver from Ati to be able to get HDMI sound working properly:

also pavucontrol Install pavucontrol for sound preferences helps a lot also...

This was the only way I could get HDMI audio working properly and selecting the sources (Analogue or HDMI) for output for specific programs to work...

hdmiaudio out may only properly work in kernel 3.6 and later (we're talking open source radeon driver). 12.10 is only up to 3.5? So closed source or else learn to upgrade your kernel (you'll learn a lot but it will take you quite a number of hours to invest).

I know the radeon driver sources say that hdmi audio is working as of 3.5 but not as universally as you'd think that would mean.
