hdmi

No matter how much advice I follow, I still cannot get any audio to come out through my HDMI connection. I've tried downloading the latest proprietary FGLRX graphics drivers, and I've also gone into /etc/default/grub and altered

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

into this

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

But still I cannot get any sound nor can I get HDMI sound output to show up in Sound Settings or Pulse Audio Volume Control. I can get video to show up just fine on my monitor through HDMI so I'm sure this problem is fixable! I know this is an old problem with Ubuntu, but any new strategies into the problem would be much appreciated.

With that being said, here are some of my specs:

Ubuntu 12.04 LTS
AMD Radeon HD 7520G

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
