As per the title, I get no sound following a fresh install of 22.04. In another partition I have Zorin OS 16 and it works just fine. I followed the instructions in this post HDMI Audio Issue Ubuntu 22.04 but it didn't work. Any help would be much appreciated. Also I am most definitely a noob. I have enough knowledge to move away from Windows & install the os, follow instructions etc. but am at loss when it comes to troubleshooting.

  • Do you have Nvidia graphics and forget to tick the option to install 3rd party drivers, etc.? If so you can install them now. May 21, 2022 at 11:36
  • See this post here, the reported bug and solution could be your issue (I had it on my system on upgrade to 22.04). And also someone else posted a different solution here too so a couple of things to try: askubuntu.com/questions/1403575/hdmi-audio-issue-ubuntu-22-04

  • Hi, thank you both your your replies. @ChanganAuto I have Intel HD Graphics 4600. In Software & Updates app I have "Proprietary drivers for devices (restricted) ticked.

  • @codlord yes, thank you. Have seen that linked and have applied all of the suggested changes. Unfortunately none of them worked.

Strong hint regarding Ubuntu hdmi problem: I had 20.04 working with sound ONLY through the NVIDIA monitor, and got no sound at all when installing 22.04.

Somebody gave a very useful hint about looking at UEFI BIOS, Advanced, Onboard Devices Configuration: HD Audio Controller (enabled!), Front Panel Type: HD Audio (no go) but AC97 works!

SPDIF Out Type: SPDIF works, HDMI ? Save changes & reset.

Well, doing this I suddenly had messed up my 20.04. Reason: in Setup -> Sound, Output Device: HDMI/DisplayPort2 - GK208 HDMI/DP worked, but Output Device: HDMI/Display Port - GK208 etc does not. To get the DisplayPort2 in both partitions, another hint was useful: sudo ubuntu-drivers autoinstall ; reboot. Alsamixer and pavucontrol never helped.

Now I still would like to have audio optionally through external speakers, and headphones ...

  • Upgraded to Ubuntu 22.04, and VIA sound card stopped working, HDMI audio only. As recommended by Göran Schultz I ran sudo ubuntu-drivers autoinstall and restarted. Problem solved!

  • @tom-197 That command installs Nvidia drivers that are usually required for proper HDMI audio but have absolutely NOTHING to do with the onboard audio device, VIA or any other, Jul 28, 2022 at 20:01

I was a bit too optimistic above with the sudo ubuntu-drivers autoinstall. My 20.04 which had worked for years with only occasional mouse-movement freeze, now started frequent mouse-click freeze (moves but no action). askubuntu.com/questions/1269473/ubuntu-20-04-freeze suggests (on a TTY terminal, ctrl-alt-F2) to do sudo apt-get purge nvidia*, and some more steps before reboot. Well, rare mouse-movement freeze has returned, but not the mouse-click freeze. I strongly suspect the nvidia drivers to be the culprit (timing issues - mostly when I have many windows/tabs open) for both mouse problems and non-hdmi audio funnies (on the Setup -> Sound I even see that live sound is delivered somewhere, I just can't get it out).
