Sometimes the game comes to a complete stop and I can't hear any noise except the game music

Hello,
My problem is that sometimes the game comes to a complete stop and I can't hear any noise except the game music. This lasts for a few seconds and I can't move or do anything, I can't turn my head or anything, and then when I come back to normal I hear all the noises at once that I couldn't hear during the time the game was stopped.
Thanks
