There is no audio output from my earphone that is connected to the monitor. I tested the earphone with another laptop and it is working fine.

I tried the following solution from similar questions but the issue still persist:

  1. No sound in Ubuntu 18.04

killall pulseaudio; rm -r ~/.config/pulse/*

It returned 21 but sound is still unavailable.

  1. No sound in Ubuntu 18.04 LTS after upgrade from 16.04 LTS

killall pulseaudio; rm -r ~/.config/pulse/*

  1. HDMI sound not working after upgrading to 20.04
rm -r ~/.config/pulse/
reboot
  1. Audio stopped working Ubuntu 19.04
sudo apt-get remove --purge alsa-base
    
sudo apt-get remove --purge pulseaudio
    
sudo apt-get install alsa-base
    
sudo apt-get install pulseaudio
    
sudo alsa force-reload
  1. sudo alsamixer Then F6 to select sound card and change the setting then reboot.

The Playback and Output Devices of pavucontrol both are using HDMI/Display Port 2 and the audio bar is fluctuating since I have YouTube running but no audio output at all. The following is the snapshot of my pavucontrol:
