[GAMEPLAY] Game does not appear in volume mixer in Windows 10

After I upgraded to Windows 10 today, I noticed that in-game, League did not make any sounds. The client itself still works, but once I get in-game, there is no sound at all. Upon going through my volume mixer, I noticed that the in-game application didn't appear - only the PvP.net client.

I've reinstalled audio drivers twice, but haven't tried reinstalling League or repairing.

EDIT: Ok I tinkered around some more and fixed it. What I did was go into my playback devices and right-click properties on speakers. Then I went to the advanced tab and unchecked "Allow applications to take exclusive control of this device."
