Bug Report Obs can't capture my mic while i am listening (Solved)

[TChen]

I want to stream my gameplay in Youtube with my voice.

My Realtek mix of headphone jack is broken for unknown reason, so i use Bluetooth headphone.
The mic of bluetooth headphone works well, when i test it with Skype Echo.
But OBS can't detect any Mic sounds sometimes.
While i record something by OBS, i can only capture the sound from my mic by playback either my laptop output.
How would i capture my voice with my mic while recording my ingame sounds?

Many Bluetooth headsets cannot simultaneously send and receive. That's not a limitation for an app like Skype because it can switch on the fly, but OBS is going to try and keep one side of the headset open all the time, so the other side will fail.

So either you'll be able to hear and the mic won't work, or vice-versa.

Thanks!
I just found my bluetooth device has two independent channels of output. One is headset, and the other is headphone.
After i set the headset as default input and output of windows, and set headset as main mic of OBS,
the problem is solved.
