In Raze, no random game sounds get plays when open main menu in game.
After start a game(new game or load savegame) on Duke3D, when you press ESC to bring out the main menu, it should be plays one of random sound, maybe weapon firing sound, or explosion sound, the sound when something squished or Duke's "ooh" sound when he's taking falling damage. It's random and you'll heard different ones when every time you hit of ESC to make the main menu appears.
It happens with vanilla Duke3D versions and all Duke3D source ports(except World Tour, since it's using its own main menu), since Raze still using original game's menu style from EDuke32 so I guess it should be exist too.
