So I downloaded and installed Fantastic Journey. I have sound at the front end, but as soon as I "start simulation" the game is dead silent, regardless of what settings I use. I've tried putting it in XP SP3 compatibility mode, it didn't help. What needs to be done to fix this? My system is an i5 4690K with a 1080Ti gfx card, 16GB of RAM, fast SSD storage, etc. High end rig. I also note the ball gets laggy/warpy which seems like it shouldn't happen either, but I'd like to fix the sound first.

OS is Windows 10, fwiw.
