Problems with AudioCapture


so I am new to this engine and wanted to use the new AudioCapture and slave some interactive audio from MAX MSP through the micinput. I had it working for a few seconds, but then it stopped working completely. Is there anything I can monitor or need two setup for the audio capture? In my knowledge unreal just uses the input I give it at the core audio, right? I use soundflower on Mac for audio routing and VB Voicemeeter on windows, but I don’t get any sound out of the engine…

I hope somebody can help me…

best regards
