Solution 1:

Try this answer. Run these commands in the terminal:

sudo apt-get update && sudo apt-get upgrade
echo options snd-hda-intel model=auto | sudo tee -a /etc/modprobe.d/alsa-base.conf

Check all mutes and unmute them through:

sudo alsamixer

Then run:

shutdown -h now

sudo apt-get purge pulseaudio
sudo apt-get clean && sudo apt-get autoremove

Reboot. Open a terminal again and type (ignore any errors with the rm command):

rm -r ~/.pulse ~/.asound* ~/.pulse-cookie ~/.config/pulse
sudo apt-get install pulseaudio
