Purely posting this to help you dear reader.
I’ve been playing edge of chaos for about three weeks with no music with no idea how to get it to work. It was annoying
The fix was to
1) Use Disk manager and set my Cd drive letter to the lowest. I had a virtual drive on E and my actual cd drive was F. so i switched my real cd drive that I war was in to E
2) download a tool called “K-lite Codec tweak tool” run it and hit fixes; then tick all three boxes and run.
Music now works for me 🙂
