I have Windows 7, and yes I checked every where to see if my mic was not configured properly - in my recording devices, on minecraft, I even went through my entire twitch settings to see if there might be a mic setting there.
Now that I think about it I maybe should have mentioned. I have a Rapoo H8030 headset, these are wireless headphones. I have no knowledge in this matter but could that effect this problem? Although that still doesnt resolve the issue with the system volume.
Oh and I also have the Razer Surround. Maybe that could also be affecting it?
Oh my gosh I just realized that. Well now I feel silly...
