I'm hoping someone can help. I'm actually quite technologically inclined, but I just can't seem to figure this out. This issue has been a mystery now for over a year. After a medical diagnosis, I decided that I wanted to start a podcast to discuss medical issues, experiences, etc. I have two XLR microphones connected to an audio interface, and one USB microphone connected directly to my computer. I've assigned mics. within OBS, I've ensured that each mic is assigned to a separate track, etc. What's happening is that the USB mic. is not picking up the primary voice sitting in front of it. The person's voice is being picked up across the room by one (or both) of the XLR microphones. However, when I mute both of the XLR microphones within the Audio Mixer section of OBS, then the USB mic. picks up the voice sitting in front of it perfectly. It seems that the USB mic is being overridden by the XLR microphones when they're not muted. Part of me feels that it's some simple setting of which I'm just not aware. If anyone has any ideas regarding how to get this USB mic. to play nicely with others, please chime in. Thanks.
