I've scoured google for an answere and have come up empty. After installing windows updates and all the drivers from the mothnerboard product page at asus, I found that I'm missing the Realtek HD audio manager or whatever it's called nowadays. I will say that I put little effort into fixing it because I don't use onboard for mucfh, but I have seen a trend towards relying on microsoft for my onboard audio even when I go through the same steps.Recently received my new custom rig from IBP, for some reason they installed a beta/preview build of Windows 11 that didn't get along with Corsair iCue and/or my void pro wireless headset so I had to reinstall Windows. The only function I used and still somewhat miss is the ability to designate each port for something other than intended. I often reset or reinstall windows and each time it's different. I have noticed over the past few years that the functionality has changed drastically. I have to ask what the realtek audio management software does that you need it for.

But I do know that when I'm streaming on discord with an external usb dac/amp and an onboard input with a modmic, I get crosstalk which has me believing that part is software based. I don't know if it's an onboard thing or something to do with the wiring after the output/input. But to address your original problem, headsets have an unfortunate side effect of bleeding output with input. Please let me know if you found out how to get the UI back.

Same thing for me i deleted the driver because i was being an idiot and thinking that if i get rid of it people wouldnt hear my youtube videos or voice chat going from my headphones to my mic.
