Need bluetooth mic with desktop audio in the same headset for VR streaming.

[Philosophist]

Hi. I love what OBS can do, but I need a workaround for this limitation. Other applications can allow me to make phone calls on my pc without stealing the audio from my headset. But OBS can only use the mic from my headset if it also takes the audio. The alternatives I've found involve using another mic, so that the headset output works, but I'm trying to stream VR. The bluetooth headset mic I use is the best for this usecase.

Is there an application that will just take my bluetooth mic audio from my computer without hijacking the output sounds from the computer to my bluetooth and then let me use it as an audio source in OBS to stream?
