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

hdmiradeonsound

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

GRUB_CMDLINE_LINUX=""

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.

Ubuntu – No sound on HDMI with Radeon driver

HDMI Audio is disabled by default on kernel 3.0+ due to a black screen on some monitors to get audio working again:

Go to the terminal and write:
```
gksudo gedit /etc/default/grub
```

Then change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

Type on the terminal:
```
sudo update-grub
```
Reboot and your HDMI sound will work again.

Ubuntu – 12.10 no audio via hdmi and video speeds up

I solved this problem! :D What I said in my first post was correct. HDMI sound doesn't work with Gallium 0.4. The new ATI drivers don't work for "old" graphics cards such as the Radeon 4200.

The solution to this problem is described here: http://www.ubuntuvibes.com/2012/10/how-to-install-amd-catalyst-legacy.html

The solution involves installation of unofficial packages. I tried it and it worked for me!

Cheers!
