Just a black box

[Zoobdude]

I'm not quite sure where I'm going wrong, I've installed the plugin using the installer, it's appeared in
OBS I can add it as a source, and when I do, I give it a audio output but I just get a black box. Any help would be really appreciated :)

Could be any number of things.
By "give it a audio output" I assume you mean you set the audio source in the waveform settings panel? did you try setting it to "Output Bus" as well?
Check if there's anything in the log file along the lines of "Failed to get audio source".
Also make sure the source isn't muted in OBS and your floor/ceiling parameters are in the right range.
And just to check if it's working at all you can set the display mode to "bars" and check the "rounded caps" option and you should see a row of circles.
