Ubuntu – No HDMI Audio on Radeon 6770 connected via HDMI to the TV


I just installed Ubuntu 13.10 and everything works great except there is no audio. I am using a Radeon 6770 connected via HDMI to my TV but under sound settings there is only analog or digital options. I would greatly appreciate any help to fix this issue.

Try the below code in terminal

sudo gedit /etc/default/grub

Edit the line





 sudo update-grub

Restart the system

Alternatively, and if this does not work, consider installing the proprietary driver for your ATI graphics card.
