Link Resolum and Garage band no sound on the output

[coco_22_96]

Hello !
I have a small issue with Resolume, and I would like to link GarageBand with Resolume. In my project, I managed to make it so that when I click on keys in GarageBand, it changes the opacity in Resolume. However, I can't hear any sound from my computer speakers. Here's a photo of my audio settings. Do you know why I can't hear anything?Thank you. very muchhhh
The connexion is ok but in the output 0 sound

Are you trying to route audio from Garageband to your speakers through Resolume?
External audio sources can't be played in Resolume currently.
