I just built a HTPC using an APU A4 5300 on a MSI FM@-A55M-E33 motherboard. I installed 12.10 and connected it through my TV. Video is fine but there is no sound. I checked the sound settings and there is no option for HDMI. I am using the recommended x-org driver. I tried fglrx and did a reboot but lost my desktop. I purged the fglrx driver and did a reboot and my desktop was restored. How can I get sound over HDMI?

  • Adding "radeon.audio=1" in /etc/default/grub didn't help

I think I found the answer here. I'm hoping for a better answer but the sound is working. The problem I have now is a watermark window in the right lower corner that says AMD unsupported hardware.

I can live with it for now but I hope it goes away with an update.

sudo add-apt-repository ppa:makson96/fglrx
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fglrx-legacy
