No HDMI Audio on Radeon 6770 connected via HDMI to my TV

Question

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.

Solution

Try the below code in terminal

sudo gedit /etc/default/grub

Edit the line

GRUB_CMDLINE_LINUX=""

to

GRUB_CMDLINE_LINUX="radeon.audio=1"

Run:

 sudo update-grub

Restart the system

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

In 'Software and Updates' have you tried enabling Additional Drivers?

I tried it and it still won't show an HDMI option in sounds.

So there's no workaround to this problem other than getting speakers? On windows I have it set up the same way and I get sound from my video card via HDMI.

Why downvote? This is the recommended way of enabling HDMI audio for the open radeon driver.

Whom ever edited it.. thank you. I probably should have made it a little more readable.

I should add that I have the proprietary AMD driver installed to enable HDMI audio without changing any boot flags, and the driver was left unchanged by the upgrade.
