So I have Ant esports ICE 511mt case which has two separate jacks for microphone and headset, but my headset has only one 3.5mm pin for both the mic and headset. So I bought a Y splitter - 1 female to 2 male, and when I connect them to the case (front) windows asks me what kind of device I have plugged in. I select mic and headset. But during all the processes, like discord, obs etc, my desktop audio also gets picked up. To test it, I start obs and add an audio capture device and select microphone RealTek (R) audio. But when I am playing a game, both the audio capture for headset and desktop audio in obs pick up desktop audio for games and everything. Is this normal? If it is then any way to solve it?
