Ubuntu 20.04: VLC player not quitting

• One way is to right click, say on an AVI file, select 'properties' and select the 'Open with' tab. Select VLC or add it and close properties. From then, all AVI files will be opened with VLS.

• For DVDs you can go to Panel menu > System > Preferences > Removable Drives and Media and go to the 'Multimedia' tab and change it from Totem.

• Detailed Answer would be

1 Click the "System" menu at the top of the screen, then click "Preferences" and "Preferred Applications."

2 Click the "Multimedia" tab.

3 Click the drop-down menu and select "Custom."

4 Type "vlc %f" in the "Command" box.

5 Click "Close" to make VLC your default video player.

Yes, @crate's answer worked for me.

VLC would mute or go silent after pausing. I went into Tools > Preferences > Audio. I had to change output module to ALSA audio output. But that, in itself didn't work. I had to then change device to HDA Intel, HDMI 0 HDMI Audio Output. Now it works great. Of course, you'll have to alter your device to what'll work on your rig. I'm running VLC 2.02 Two flower on Crunchbang Waldorf X64.
