No sound and does not appear in sound mixer - Windows 10

I just recently installed Minecraft for Winodws 10 via the Microsoft App Store. 

I have no sounds at all in game and the game also does not appear in the volume mixer. 

I have tried searching several forums for a solution to this issue.

I have updated Windows 10, my sound drivers, my motherboard drivers, and Java. 
I have tried running the game with "Exclusive Mode" checked and unchecked in audio properties. 
I have tried uninstalling and reinstalling the game. 
I have tried disabling all audio devices except for one to see if it preferred a specific audio device.
I have tried the game in stereo and surround sound. 
F3+T, F3+S, F3+S+T, all do nothing except open a chat window. 

The volume is all the way up in the game. 
There is not setting for "mipmap" in the version of the game I have.
And yes, I have tried turning it off and on again. 

I have been trying to figure this out for hours.
