ubuntu 22.04 audio output not working (dummy audio)

I have just upgraded my ubuntu to 22.04 but the audio is not working. In the setting, the audio option has only "Dummy Output" and the test fails.

I have tried to do what is reported here and here but both do not work.

Thanks

I have found this solution here.

Firstly, I have kill pulseaudio:

pulseaudio -k

After that, I have check if my laptop uses snd_hda_intel:

lsmod | grep snd_hda_intel

Luckily, it does.

I have, hence, run the following command:

echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf

Finally, I have switched off and switched on my laptop. It seems that a simple reboot is not enough.
