Loose sound

Hello:

I am playing killer instinct and after 5 minutes of gameplay. The sound disappear. Competently without sound. This happened after I bought season 3.

My specs in pc
I5
16 gigas ram
Nitro r9 390
Please let me know

See if this simple trick helps:

-Minimize KI window.
-Maximize KI window.

Many times my KI starts without sound, and because it is “windowed full screen”, it may loose system/window focus. Doing the above will put the system/windows focus back into the KI full screen window.
