I had the same issue and it was very sporadic.
The way I ‘fixed’ it, was go to tools > preferences (simple settings)
Click on HotKeys at the top.
At the bottom of that screen is:
Mouse wheel vertical axis control
Mouse wheel horizontal axis control
Change both to ignore. Click Save and restart VLC.
You wont be able to turn up/down volume with the mouse wheel, but I have had no more volume problems.
