Can't get HDMI audio working Ubuntu 22.04

[MAFoElffen]

Try this

pactl set-card-profile 0 alsa_output.pci-0000_29_00.1.hdmi-stereo-extra5

That tells it to set it to that profile, unmuted.

if that does work, but it changes each time you log in, then: Activites > Startup Applications > Add ... Add that commamd. That would reset it each time you logged in.

If it still doesn't work, then

sudo apt install -y pavucontrol
pavucontrol

Set device. Ensure it is not muted. Test by reseting the volume to full... Should hear it while resetting the volumes.

I tried both methods, still no luck! This is so weird. The pactl command says the device is invalid. I already have pavucontrol, I set it to the correct device and turned the volume all the way up, nothing!

[MAFoElffen]

That doesn't make sense. The list show sinks is ID'ing with that, but not being able to set it. Then the Volume Level widget is showing it, but nothing coming out. What the heck?

This is a mystery. Is there any other devices showing in the Volume Level widget to test for sound?

[dwstix86]

I know! I even copied and pasted the text to make sure there weren't any typos... Tried unplugging HDMI, plugging back in, nothing. The only other audio output device is the SPDIF digital ouput but there's nothing connected to that, and no volume either.r.

Should I try reinstalling Ubuntu?

I thought maybe it was the Radeon drivers but I already reinstalled the latest version

[MAFoElffen]

Let me ask a friend about it...

Ok thanks!

Sorry work has gobbled all my time as of late.
If your still around and unsolved, please show this:

cat /etc/default/grub
### And
cat /proc/asound/cards

Mine is a bit different than your model IE:

 0 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xd1000000 irq 94
 1 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xd1540000 irq 95
 2 [Dock           ]: USB-Audio - UOEOS Laptop Dock
                      DisplayLink UOEOS Laptop Dock at usb-0000:06:00.4-1.2.1, super speed

It may also be worth opening pulseaudio-volume-control if it's installed (if not install it with sudo apt install pavucontrol then have a look in the right hand tab, Configuration, of that where it should show several HDMI options, all assuming that you have an HDMI port of course.

Mine shows two profile options in dropdown boxes, one for Analogue Stereo Duplex and the other for Digital Stereo (HDMI) Output

It is possible that the Digital one may be set to Off instead of one of the needed HDMI options.

See screenshot of my pavucontrol window.
