I built a new PC about a month ago, and have been using speakers as a primary Audio source. However, I bought a Turtle Beach PX21 headset, and all I can do is watch Netflix/Other media ETC. I can't use Skype or Steam calls because it won't register the headset as a recording device. Why is this ? I was using this as a reference: https://www.techspot.com/community/topics/turtle-beach-px21-dpx21-computer-problem.162408 ,but they don't go over my problem. Thanks !
