I have potentially fixed this issue:
I had this bug, tho I heard this weird sound on the main menu just as it loaded, and went thru the following trouble shoot:
- Ran as admin
- Verified integrity of the install twice
- Rebooted computer
Finally after almost pulling my hair out I just clicked on settings (win10), Devices, Sound Settings and then finally Sound Control Panel.
I got a notice window that something was off with the driver or enhancements weren't working, and then the sound just returned when I launched the game again.
Really weird bug, I hope it doesn't return.
I made an account on this forum just to make this post, didn't want someone else to get the computer-rage over this bug :P
