No HDMI sound, other sound is Okay Ubuntu 21.10

[gds1960]

HDMI shows up on the list of audio outputs, but when I choose it, the sound doesn't work at all. I checked to make sure nothing was muted and sound was turned up to 100%. I am pretty new to this. I have mainly been using windows for almost 26 years. I used Fedora for a couple of years, more than 10 years ago. I know a few of the commands for displaying information, but not all of them. I have this wonderful, hdmi sound system and can't use it at all. Any suggestions at all would be helpful.

Further Explanation:
Gnome
Open Settings app
Open Sound menu
Check Output
Output Device: HDMI/DisplayPort - Built-in Audio
Configuration: Digital Stereo (HDMI) Output
Click "Test" Button, Click all speaker buttons one at a time and they light up and go off after 2 seconds and I hear nothing.

Almost all sound output sources are dead. The only output source that works is the front headphone

[SeijiSensei]

What is the HDMI source? A video card from NVIDIA or ATI? For NVIDIA at least, you can only get sound with the proprietary driver. Go to Settings > Driver Manager and see if the application installs a new driver for your card.

[#&thj^%]

Along with Seijisensei suggestion, Please give this a shot:
By adding "snd_intel_dspcfg.dsp_driver=1" to "/etc/default/grub"

sudo nano /etc/default/grub

after

GRUB_CMDLINE_LINUX_DEFAULT "snd_intel_dspcfg.dsp_driver=1"

update grub

sudo update-grub

reboot >>> any difference?

Thanks for trying, one more output please:

lspci -nnk | grep -i -A7 audio

Paste back wrapped in code Tags please.
See my signature to see how if in doubt

I did not do anything, except make two or three rounds of updates and now my sound works perfectly.

Great News.
I was about to send you here: (Your good to go so just ignore)
latest sof drivers are here:
https://github.com/thesofproject/sof-bin
and drivers are not distro specific packaged so they can be used with any distro.
Sof drivers work with Intel Tiger Lake-LP Smart Sound Audio after additional configuration.

By the way this is a Rocket Lake CPU. After turning off my computer overnight, the problem returned.
