These commands work for me:

 

pactl list short sinks #shows available audio outputs
sudo -H nano /etc/pulse/default.pa #opens the file for editing
set-default-sink alsa_output.platform-hdmi0-sound.stereo-fallback #set your default audio output
rm -r ~/.config/pulse #delete all files in this folder

reboot
