Microphone no longer pust-to-talk when routing to headphones

[sampSCS]

With my speakers set up through Win10 x64 as my default playback device and the Headset microphone not set as the default recording device, I start a game, then used your application to route the sound to the headphones. Unfortunately, I started getting every noise picked up by the headset microphone through the headphones.

Previously, I would use the OS's sound applet to change my default playback device from speakers to headphones (with the Headset microphone not set as the default recording device) and the pickup from the microphone would only function when the push-to-talk button was pressed, and its sound would never play through the headphones themselves.

I also tried using the duplicate function to have sound routed to both speakers and headphones, but had the same result (with noise from the microphone coming from both speakers and headphone).

Is there anyway I can use your app to have game audio routed to both speakers and headphones, without my microphone behaving this way?

Does it happen in every game or only that particular one(also, what's the name of the game)? If it happens in every game, then it's certainly a bug in audio router, but if it only happens in that specific game, then it's probably a bug in the game.

Just confirmed that this problem occurs in at least 2 other games
