I'm not an expert on this topic what so ever , but from reading all possible things of what could be causing it ( memory , sound ) i just switched 2 thing around in settings and i have not had the problem anymore since then.
So what did i do : 1 ) Switch my memory allocator to windows system in additional parameters . 2) in audio option in game i dropped my sound sources to 80 .
I honestly didn't do more search in to or did more testing .
I can't guarantee if this works for you , but i guess you can try this if you're still looking for a fix.
