It all started when I installed Windows 10 on release day. (I was using windows 7 before). I downloaded mumble and then all my games and started playing with friends. After a while I noticed that my friends weren't responding to me I alt tabbed and realized my push to talk wasn't working (this goes for every voice program, the same thing happens the push to talk key stops working). In my Recording options the mic isn't disabled.

When I go into recording devices after it stops working when I speak I do not see any green bars, when I go to steams voice test and nada, no green bars. To fix it I either go into Mumble settings and just hit 'apply' or I open up the mumble audio wizard and close it right away and my mic will work again along with push to talk. For some reason this makes my mic work again.

I've tried a fresh install of windows 10, I've tried different mics, different sound cards and the same thing keeps happening. Before I reformatted it got so bad it was happening every 2 minutes. Now it happens every couple of hours and progressively happening more often.

To me it seems something is disabling my mic and doesn't re-enable it. EventViewer isn't helpful there is no entry for when it happens. It happens when I'm gaming, or even when I'm not even on my pc doing anything.

I feel like I tried everything. I've been googling fixes and working fixing this for two weeks with no luck. Any help would be appreciated.
