I'm using an Astro Mixamp Pro with my Xbox One and connected the MP3 Port on the mixamp to my laptop's headphone port so I can hear music that comes from my laptop. If I do something like sing along, I hear the music first and then my voice about 1 second after. I use my laptop's webcam also and my mic syncs up perfectly with that. My microphone is connected to my PC. How can I sync audio from the mixamp with my PC mic?
