Ubuntu: 20.04.03
Kernel: 5.15.13
Motherboard: MSI Pro Z690-A WIFI (MS-7D25)
Processor: I9 12900k

My problem is with the sound through the HDMI.

I have already tried several things and possible solutions, with updating x-org, using ppa with new drivers, restarting pulse-audio, downloading a pulse-audio driver, and several possible solutions that I found here and elsewhere.

None worked for me, in the configuration part, it did not even appear in the audio part, the hdmi. The video looks perfect.

I updated to kernel 5.15 and there I recognized some things (wifi, bluetooth), but none of the audio over hdmi.

  • When you go to Settings->Sound does HDMI show in the list of output devices?

  • @Bovine No it doesn't even show up

  • My only other thought would be to try a different HDMI cable and also try connecting to a different monitor or a TV to see what happens.

  • Cable and hardware are working properly. It's a controller issue

Solution:

You have to add the following parameter to the kernel:

i915.force_probe=4680

For that you have to do:

sudo nano /etc/default/grub

Inside add the code to the line, it would look similar to this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.force_probe=4680"

You save the changes to the file and then update the grub

sudo update-grub

Then you restart and you should see the hdmi option working:

sudo reboot now
