No Sound after reboot

[Jredmartin]

I have a Dell Lattitude 5510, running the Zorin-OS-18 Core.
New Zorin OS Install (about a month.)

After installing Zorin it ran great -everything worked like it was supposed to for a few weeks. Videos played with sound just fine, but suddenly I tried running a video for a weekly class I teach and I cant get any sound.

I checked sound settings and keep getting "Dummy Output "with no other options to select.

I checked the forums and found several suggestions which I have tried. The only thing that works, is after login I have to use a terminal command to force reload ALSA using this command: "sudo alsa force-reload". I get sound only after that. However I cant make it stick. Everytime I boot up the laptop, regardless of what I have tried will not remember the setting, I have to force reload the alsa.

I even tried this following suggestion I found on the forum:
"Automate the ALSA Reload Script
If the issue persists, create a systemd service to automate the fix:

1. Create the service file: sudo nano /etc/systemd/system/fix-sound.service
2. Add the configuration to force-reload ALSA, with a 5-second delay to allow services to load.
3. Save, exit, and enable it: sudo systemctl daemon-reload and sudo systemctl enable fix-sound.service."
   this is the result:
   
   
   
   That hasnt help to create a fix.

This is the aplay -l output:

Any advise is appreciated.

Hi having done some searches for issues with that specific card on different distros the general consensus is to install sof firmware:

sudo apt update && sudo apt install sof-firmware

if things worked for a while and then quit it could be a kernel update issue that you could test out by reverting to an older kernel through advanced options.
