Hello, I've recently reinstalled train simulator classic on a fresh copy of windows. I've been hearing occasional audio crackles/popping in the background. They aren't particular loud, and seemingly random, however moving the camera around and putting it in certain directions seems to increase/decrease them happening. The game is not unplayable, but enough to be a bit distracting (especially using headphones) - bit like occasional stutters in the audio. I've done all the usual things like installing drivers etc. Don't have issues with general use, just train simulator. I've done some googling, it seems some people reported similar when 64 bit version first launched, but I thought this was fixed by now. Just wondering if anyone else has experienced similar? Or any advice? I'm wondering if the issue has been there all along and I've only just started to notice it as I haven't played TSC in a while and am coming back to it.
