You have to tell us more about your system. My crystal ball says you 
probably missing some firmware for a sound adapter from Intel.
Install firmware package from a 'non-free' section and see if that will 
help:
     # apt install firmware-intel-sound alsa-utils
To test the audio use 'speaker-test' utility:
     $ speaker-test -c2 -t wav
Also check if any channels were accidentally muted using 'alsamixer' 
utility.

If you still don't have any sound, send output from commands below with 
your next message:
     $ lspci -knnv | grep -A6 Audio
     $ aplay -l
     $ aplay -L | grep -A1 ^hw:
     # journalctl -b -g pulse

With kindest regards, Alexander.
