Hey!

This seems to be a routing problem.

I can give you some hints:

Resolume just takes that as the input but it’s not routing it to output (I don’t know if that’s in the feature set of resolume - but I wouldn’t count on it anyways).

Think of the Cycles as a audio interface… maybe try to set MacOS’ output to Cycles (it was always a bit buggy for me tbh) or if you don’t like that try Blackhole:

and or try with aggregated device in the Audio Devices menu to mix the signals.

Cheers!
