UPDATE
I was able to fix the slider problem …
you have to update resolume to the last version
and now I can choose between
input 1 and input 2 …
Anyway, if someone finds a better way to see and choose the audio ports that are active inside resolume, that would be great!!
@jmcc Thanks for your answer!! I did not understand how it worked in the beginning, but now I see it more clearly.
you have to write the exact name in the parameter and work okey …
thank you very much for the example too !!
