I've recently purchased a new gaming headphone, with a mic. I plugged it in, went to control center, made my device the default communications device. I run my headphones from: Pc to HDMI to Monitor To Headphones input. In the "playback" setting of the sound window it has the monitor present, but the monitor inst present in the "recording" setting. The monitor is the only input I have, please help!The mic is responsive, it has built in testing for that. I hear audio, but can't speak.
