How to problem occurs:
I was watching a course and suddenly my laptop rebooted and after that, I have no sound and 'Dummy output' Showed to me.
I tried almost all google solutions and none of them working, I would like to figure out the problem and make it work, Anyone is here can help me with this?

`aplay -l` output: https://pastebin.ubuntu.com/p/X3M23w6b4d/
`pacmd list-cards` output: https://pastebin.ubuntu.com/p/CGss74Dt4n/
`pacmd list-sinks` output: https://pastebin.ubuntu.com/p/ntX3wWDKN2/
`pulseaudio -vvv` output: https://pastebin.ubuntu.com/p/JN2vz4Pq8Z/

As you see in logs (aplay output) is just HDMI cards, not my main card and PulseAudio says: pa_pid_file_create() failed.
