Question / Help DJ LiveStream using OBS and MacBook Pro

[Tofty]

Hi everyone. Im using OBS Studio to livestream DJ sets and I think im nearly there with my setup which is listed below

MacBook Pro using OBS Studio
MacBook Air using Traktor and Pioneer CDJs in advanced HID mode
EpoCam Viewer to allow iPhone 11Pro as Webcam
Traktor Audio 6 Soundcard
Booth Out from my Pioneer Mixer into the line in on the SoundCard

I streamed last night, however I found out after that it was picking up external sounds (me talking for example).

Was this because I didn't mute the already assigned mic in on OBS (although I removed it) or is the sound being picked up from somewhere else?

Thanks all. Danny

Did you mute the MIC of your iPhone in OBS since you're using it as a Capture Device it'll capture video AND audio
