I just installed Ubuntu 13.04 on my media PC, and I successfully installed Catalyst 13.4 and everything works great except I get no sound out of HDMI out. In the sound dash there are 3 options but none make any difference: there is digital output (S/PDIF) ,headphones, and analogue output. Any help is appreciated. Thank you in advance.

It's bug https://bugs.launchpad.net/bugs/1169761
The kernel team introduced this by picking and choosing patches. The generic 3.8 kernel doesn't have it, and Ubuntu 13.04 kernels older than a mid-April are also ok.
I'm sure this is getting a lot of attention since it affects so many.
