So this has been affecting me for a few months but it recently got bad. What happens is whenever I do something in the game for the first time the game freezes for a second or two and the audio loops for a second or two. By something new I mean when I do something for the first time that day. It includes me pressing escape, changing weapons, etc. If you need anymore information I'll try to provide it.
