intel hdmi sound does not work on ubuntu 20.04

us flag

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

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
