As I'm away from my computer, and it's been a while, this will be from memory - so it may not be completely accurate.
Anyway, I've had problems setting mic levels. I had the problem in Win 7 with my Sennheiser headset, and in Win 10 with my Rift. Essentially, the problem came down to the mic levels being way too high and picking up extraneous noises like my breathing, the TV at low levels, cars driving by, and etc. If I went into properties and clicked on the levels tab, there was a slider. If I adjusted the level down and hit apply, it would never take. Instead, I would have to go through some process of speaking very loudly into the mic to get the level to go down and stay there. Then, I'd make a recording and breath loudly or whisper, and then speak normally, and keep making adjustments until I could only hear the normal speaking. This process seemed to work well with voice comms with my Sennheiser, but I haven't tried in in game with my Rift yet.
So, any thought about what I'm doing wrong? Why can't I get the slider to work? Also, there was something about allowing "exclusive control". What does that mean and how does that affect ED and using TS or Discord, and etc.
Also, will Window save all these settings for different devices when you disconnect and switch things around? I may want to take off the Rift headphones and disable that mic, and go back to using my nice headset.
Thanks.
