Ok I have a very complicated setup it seems like because no one can help me. What I have is my elgato capturing my ps4 and taking the audio from that. What I want to do is use my Astro a40s USB into my computer and use them as a mic. I have that working but when I try and get my skype in the chat it doesn't work. It works but only if the obs volume is up in the system sounds also will give an echo like over and over repeaditly. Please someone help me get my Skype and music in the stream. Please note it worked with my aux cord plugged in from the stream port on the mix amp to the line in on my PC but it was giving a Buzzing sound and also a delay due to matching the mic with my cam.
