I've been having issues with my laptop an HP Envy 15z j-100 and static in my headphones. I have a pair of Turtle beach z11s and when I test the headset through a program that can record my voice I always hear static behind it. I also went to recording devices, listened to the audio coming from the microphone and heard static also. My other issue is that I can not set my headset as the default playback device, I can only set it to default communications and the speakers are the default playback. If I disable the headset in playback devices the audio comes from the headset but if it's possible i'd love to correct it anyway. I tested the headset on my PS4 and there is no static. They both connect by a single 3.5 male. The headset has a choice of splitting the voice and audio but my laptop only has a single port.
