I found bug where the audio turn into high frequency distorted sound when you go back to main menu.
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!
