    Dell Vostro 5590 Ubuntu 20.04 audio not working

After updating Ubuntu from 18.04 to 20.04 I have no sound on the notebook Dell Vostro 5590.
I completed these steps, reboot PC and sound problem was fixed:

Purge Alsa and PulseAudio using the command:

sudo apt-get remove --purge alsa-base pulseaudio


Install Alsa and PulseAudio again:

sudo apt-get install alsa-base pulseaudio


Reload Alsa:

sudo alsa force-reload

After doing step 3 my PC was freezed. Mouse cursor moved, but PC didn't react on mouse clicks and keyboard.
I pressed Power button and hold it approximately 10 seconds. Notebook rebooted.
Sound problem is fixed.
