20.04 sound stopped working

Not entirely certain what happened. I am running 20.04 LTS and the sound just stopped. I have tried many different solutions found on line, but to no avail. I did check https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/693256 but that didn't resolve the issue either.

pulseaudio seems to instantly respawn . I have been through multiple reboots.

I have checked alsamixer, all looks good.

Any questions or advice is greatly appreciated.
