Sound issues

Linux Mint moved to a new sound server called Pipewire.

To check which sound server is running, use the following command:

inxi -A

If you're unable to get the sound working, you can try to go back to the 
older sound server called PulseAudio.

apt purge pipewire pipewire-bin
systemctl enable --user pulseaudio
sudo reboot

Upstream bug report for choppy sound over HDMI:
