After I power on my laptop and try to play some music I faced up with "Dummy Output" and I do some search and tried some famous solution and none of those worked for me, anyone can help me with this?

Os: Ubuntu 20.04

Kernel: 5.4.0-42-generic

Also, I tried all solutions from

and none of the solutions worked for me.

When I run this command pacmd list-cards I get this: https://pastebin.ubuntu.com/p/CGss74Dt4n/

and the output of pulseaudio -vvv is: https://pastebin.ubuntu.com/p/JN2vz4Pq8Z/

the output of sudo play -l is: https://pastebin.ubuntu.com/p/X3M23w6b4d/

I don't even know if it's related to the problem or not, but after trying any way to solve the problem, none of them worked, but after force shutdown, the problem was fixed and it's working properly now

UPDATE March 2022:

This issue happened to me again, I was watching a course and suddenly my laptop rebooted and after that, just dummy output showed to me and there is no sound.

Solved: I purge all PulseAudio by sudo apt purge pulseaudio* and hard shutdown and installed it again and hard shutdown, weird! but it worked.
