Change output module in Tools → Preferences → Audio from Auto to Pulseaudio or Alsa.

alternative edit config file:

vi ~/.config/vlc/vlcrc

# Audio output module (string)
aout=pulse

Gnome uses two lists to register applications to file types located in:

• /usr/share/applications/mimeinfo.cache
• /usr/share/applications/defaults.list
• ~/.local/share/applications/mimeinfo.cache

#manually
sudo vi /usr/share/applications/mimeinfo.cache
sudo vi /usr/share/applications/defaults.list
vi ~/.local/share/applications/mimeinfo.cache

#or via sed:
sudo sed -i 's#video/webm=#video/webm=vlc.desktop;#' /usr/share/applications/defaults.list
sudo sed -i 's#video/webm=#video/webm=vlc.desktop;#' /usr/share/applications/meminfo.cache
sudo sed -i 's#audio/webm=#audio/webm=vlc.desktop;#' /usr/share/applications/meminfo.cache
sed -i 's#video/webm=#video/webm=vlc.desktop;#' ~/.local/share/applications/meminfo.cache
sed -i 's#audio/webm=#audio/webm=vlc.desktop;#' ~/.local/share/applications/meminfo.cache

These scripts make VLC behave like MPC-HC, ie when you open a file with VLC in a folder, it will automatically add all the files in this folder to the playlist (starting with the opened file, then sorted alphabetically), so that you can use Previous and Next to navigate through the folder.

https://github.com/x-hgg-x/Utils/tree/master/VLC%20Create%20playlist%20from%20file

Notes
Due to internal behaviour of VLC, you cannot replace current playlist by another, only append it. Therefore the script must kill existing instances of VLC to launch a new playlist, so it works only when VLC is in one-instance mode.

You may want to activate the loop option in VLC preferences if VLC is configured to play the next track automatically. (Tools → Preferences → Show all settings → Playlist → Repeat current item)

or edit ~/.config/vlc/vlcrc:

vi ~/.config/vlc/vlcrc

# Repeat current item (boolean)
repeat=1

Copy vlc.sh in ~/.local/bin directory and mark it executable, then copy the desktop file of VLC /usr/share/applications/vlc.desktop to ~/.local/share/applications/vlc.desktop and change the field Exec to the path of vlc.sh (remove argument –started-from-file %U). Known extensions are stocked in variable $extensions.

sed -i 's#Exec=/usr/bin/vlc --started-from-file %U#Exec=/home/'$USER'/.local/bin/vlc.sh#' /usr/share/applications/vlc.desktop > ~/.local/share/applications/vlc.desktop

note: source from github adjusted to sort numbers as Versions like nemo file manager does.

~/.local/bin/vlc.sh

#!/bin/bash

# if the filename does not have one of the extension above, launch vlc with provided filename

# launch playlist
IFS=$'\n'; read -d '' -r -a files < /tmp/vlc.m3u; vlc --norandom "${files[@]}"

chmod 755 ~/.local/bin/vlc.sh
sed "s#Exec=/usr/bin/vlc --started-from-file %U#Exec=/home/$USER/.local/bin/vlc.sh#g" /usr/share/applications/vlc.desktop > ~/.local/share/applications/vlc.desktop

Copy vlc.ps1 and vlc.bat in your home directory, then you can open your video/audio file with vlc.bat like this :

vlc.bat video.mp4.

You may want to run Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy UNRESTRICTED once in a powershell terminal to allow exectution of powershell scripts.

You can check if the variable $vlcPath is correct in vlc.ps1, and modify known extensions with the variable $Extensions.

vlc.bat

@echo off
powershell -File %USERPROFILE%\vlc.ps1 %1

vlc.ps1

# kill other instances of vlc to keep playlist clean (one-instance mode)

if ([string]::IsNullOrEmpty($filename)) {& $vlcPath; exit} # launch empty vlc if no argument provided
 
# parse argument
$filename = Resolve-Path -LiteralPath $filename
$dirname = Split-Path -LiteralPath $filename

$count = $($filelist | Measure-Object -Line).Lines
$position = $filelist | Select-String -Pattern $basename | ForEach-Object { $_.LineNumber }

So put the file in ~/.local/share/vlc/lua/extensions. I call it DeleteFile.lua.

When you start VLC you get a new menu item: View > Detetefile. It is this last step I was missing.

It now searches for a dir called .waste in the dir of the file and any (grand*)parent dirs, and moves the file there. So you need to create a dir called .waste.

When you start VLC you get a new menu item: View > Move currently playing file into wastebasket.

WasteBasket.lua

--[[
INSTALLATION (create directories if they do not exist):
- put the file in the VLC subdir /lua/extensions, by default:
* Windows (all users): %ProgramFiles%\VideoLAN\VLC\lua\extensions\
* Windows (current user): %APPDATA%\VLC\lua\extensions\
* Linux (all users): /usr/share/vlc/lua/extensions/
* Linux (current user): ~/.local/share/vlc/lua/extensions/
* Mac OS X (all users): /Applications/VLC.app/Contents/MacOS/share/lua/extensions/
- Restart VLC.
- The extension can then be found in the menu:
    View > Move current playing file into wastebasket
