Sound problem in MK 11 (Mortal Kombat 11)

Hello! And so start the problem started when I installed yesterday MK 11 on my own so I will say not even so and weak computer game pulls me maximum graphics in full hd resolutions, and it already means something so that's when I start playing the storyline of the videos in MK 11 I in a fraction of minutes 2-3 begin to cool frees, then lag give out along with the sound and just as the sound of the glitch will give a lag of the game in a fraction of a second. and I can not understand the reason for such lag the rest of the modes I go perfectly sound perfectly etc, but the storyline constantly suffers sound, can anyone faced with this problem and help. (My configuration is RX 570/i5-3470-16 gb of oise)
