Volume control for moviestim3 still not working? VLC issue with moviestim2

As with the title, I am unable to control movie volume when using MovieStim3. The source code stated that this hasn’t been fixed so I am assuming it’s still the case right now?

I then tried using MovieStim2 instead and ended up with another issue of 'AttributeError: module ‘vlc’ has no attribute ‘dll’. As I am using the standalone version (v3.1.5), installing python-vlc via anaconda didn’t do the trick.

What would be the best solution for me right now?

Bump, if anyone is aware of a solution to adjust volume using moviestim3.
