    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.
