While playing RWR the sound works no problem, but soon after playing for about 5-10 mins the sound just cuts. I restart RWR and it is working but then it happens again. I also watched a 20 min video on youtube and it seems to be fine. I think it might be the game.

I've never heard of that issue before. Does it happen when playing vanilla or a mod?

It happens on vanilla, never dealt with any mods with it yet. I tried to reinstall it and that also didnt work but I did realize that once the sound was cut off there was a sound that constantly repeated every few secounds, like a beep sound

I managed to fix it, sorry for wasting some peoples time. All I had to do was get a new audio driver
