I've looked this issue up a bunch, but most of the solutions are unity solutions. i am using XFCE and Can't seem to find the new ubuntu settings control panel.

I am using mythbuntu, and I upgraded from 11.10 to 12.04. Now I am not getting audio over HDMI. I'm sure it's a simple problem, but all the solutions I've looked up have not resolved it.


It's a kernel problem

Do this an the sound will come back

No sound on HDMI with Radeon driver

  • This resolved my situation. After I added this to my grub launch flags all I had to do was configure mythtv to use HDMI out (which previously did not produce sound). – BloodyIron May 17 '12 at 15:32

Are you using an nvidia video card for your HDMI output? If so, refer to this solution, it might just be a driver issue.

How do I get 1366x768 resolution working on 12.04 with nvidia GTX275

Let me know if this solves your problem.

  • It says in the title, right beside HDMI, "AMD". – BloodyIron May 17 '12 at 15:31
