I'm trying the live CD 12.04.3 LTS, but can't get sound to work from hdmi speakers and amd ati radeon 6000 series graphics cards. I downloaded the linux driver from the amd website, called amd-driver-installer-catalyst-13-4-x86.x86_64.run. I extracted the file, then double-clicked on it. It looks like a script file. How do I install it?

Will this solve my sound problem?
