Hello everyone,
I don't know why but from 3 or 2 days I don't have sound anymore when I go to te settings (sound) everything seems like normal but when I trying my devices no soung go out from speaker (or headset) only alert sound work 
! google, opera ,vlc, spotify and many more not working
can you help me
Kernel update ?
Did you mute it prehaps ?
Did you try alsamixer to see what is going on ?
I second this suggestion. It is not unusual that after an update - sound gets muted.
I saw zorin got an update 2 days ago
No I didn't mute it sounds alerts still work
I don't know alsamixer but I can check
What do you mean by gets muted ?
By me ?
It's muted ^
No, the installation of updated packages somehow causes it to get muted by the system.
Do you use dual boot ? windows and zorin ?
If yes -> pulseaudio - No sound from line-out in Ubuntu 19.10 on ALC1220 - Ask Ubuntu
Some users says downgrading kernel might work too -> Live Boot Realtek ALC1220 not detected - Linux Mint Forums
yes I do
Headset is showing [MM] i.e. muted in your alsamixer screenshot. Unmute that channel by selecting it and typng "M".
If you think sound has been turned off since kernel update, have you tried selecting the previous kernel at at boot?
