THX Spacial Audio

When i’m listening back through my headset,  i can hear the music or video i’m listening is coming through mic . The way i found this out by looking at the sound control panel i could see movement on my mic where it says “ Test your microphone” enabled or disabled with my headset mute button. Trying to figure out how to stop this from happening . I have tried to disable  the speaker but then no sound comes out . Both the THX speaker and your original speaker have to be on at the same time  in order to function . I’ve also tried the Realtek settings to split the connections. If anyone has any ideas or a solution would be greatly appreciated !
