Type in terminal:

sudo apt install pavucontrol

To restart machine type:

sudo systemctl reboot

If after restart there will be no sound, type in terminal:

sudo nano /etc/modprobe.d/alsa-base.conf 

add

snd-hda-intel model=clevo-p950

to the end of this file, save with Ctrl+o and exit with Ctrl+x.

Restart machine.
