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.

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 ...
