No Audio After Upgrade – Fix No Audio After ‘apt upgrade –with-new-pkgs’ on Ubuntu 20.04 LTS

After yesterday upgrade with command

sudo apt-get -y --with-new-pkgs upgrade

i have Dummy Output in Output Device and now i hear no sound, either through speaker or audio jack.

i have new kernel 5.8.0-34

inxi -SA output is:

System:    Host: matteo-swift Kernel: 5.8.0-34-generic x86_64 bits: 64 Desktop: Gnome 3.36.4 
           Distro: Ubuntu 20.04.1 LTS (Focal Fossa) 
Audio:     Device-1: Intel Sunrise Point-LP HD Audio driver: N/A
           Sound Server: ALSA v: k5.8.0-34-generic 

it seems that audio driver is missing (driver: N/A) but i can't find it online
