[VivoBook Flip 14 TP410UF, Realtek ALC294, Speaker, Internal] No sound at all

[Amirhossein Roudgar]

The sound was working just fine. I didn't work with my laptop for about half an hour and I didn't change anything that I can think of. But suddenly, there were no sounds anymore.

Sorry, forgot to add aslainfo.

Sound suddenly works again without doing anything.

I disabled unattended-upgrade since last time, so maybe it was not related up updates in the first place.

I have a vivobook m7400qe and have similar problem.
Audio never worked from speakers or headphones jack. Mic does work.

The solution at this link worked ONCE, then never again
https://askubuntu.com/questions/1394452/sound-not-working-on-ubuntu-20-04-asus-vivobook-pro

So it should be a configuration related issue.

Any other solutions found over the web don't work.
