this is also happening to me, I'm on w10 with the latest build and anytime I open the game, the audio crashes creating the most awful earrape I could ever suffer, at the beggining it was just a bit louder, but everytime I reopen the game, the music gets louder. Luckily by just entering the sound menu it fixes, but I always get scared when I open it. I could record a video and upload it to see if you could know what's happening...
Besides this, the game is incredible and I'm enjoying it a lot!
