Can you check with pavucontrol-qt (KDE-only; use pavucontrol-gtk, if you’re using Gnome) whether your VLC audio stream is visible to PulseAudio?
In KDE/Plasma 5 you also can use the volume widget near one of the desktop corners; keep an audio file playing in VLC while checking — VLC should then get listed in the »Applications« tab in that widget.

I’ve also found the following articles helpful to fix audio issues:

Hope this helps.

Did you read the appropriate sticky from the top threads in this Multi-media subforum?

And did you then do the “switch to Packman”?

Uninstalling and installing VLC is not advised in those threads AFAIK.
