Kinda confusing at first, but that is what is going on. So you lose game audio which wants the stereo audio output. Everything working (after some trial and error). On OBS, Desktop audio is playing gaming/browser/etc sounds, Mic1 is Blue Yeti, mic2 is Foobar (set to go thru Cable-A Input (VB-Audio Cable A). Output: VB-Audio Virtual Cable is default. Your headset then says, oh no, my microphone is on, I need to change the audio output to hands free. Input: VB-Audio Virtual Cable is set to play thru my speakers/headphone. Ok, so why did I lose audio? The game is using your stereo audio output, The game also uses your microphone in game, so once you start playing the game… the game says… “hey, I need a microphone” and it switches your microphone on.

Microphone is on, Headphones detect this and enable Hands Free audio output (turning off the stereo audio).

Stereo Audio is being used (microphone is off).

So we force disabled the headphones microphone so it wouldn’t automatically switch to the Hands Free audio which makes us lose the Stereo audio the game is using. When a your headset microphone is detected in use, The hands free feature disables the stereo output and switches it to the hands free output.

When an application detects that a microphone is needed, the headset will turn on the microphone and switch your audio output to the “hands free” output (hands free lowers the quality of audio because it needs to use some of the Bluetooth signal to send microphone input). What happened? Most Bluetooth headsets cannot deliver stereo audio and receive microphone input at the same time. scroll down to your headsets microphone, right click and disable (Or better yet, set it to an alternative microphone)
