How to get Sound Over HDMI With ATI

  6 years ago

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:


Open grub as administrator with a text editor.

Then change the line:




Type on the terminal:

sudo update-grub

Reboot and your HDMI sound will work again.

Can't edit the file. It's locked in the GUI. How do I get permission?

Thanks for your comments.

@Infinite_Waffle: I'm sorry this didn't work. At the moment I don't have my laptop anymore to test again...

I hope you will find a solution.
