I've found a fix which might work for some other mods which use stock sounds included in a .sfx file during their development. I copy/paste the Sound folder located in "Star Wars Battlefront\GameData\Data\_LVL_PC" to "Star Wars Battlefront PC Dedicated Server\Data\_LVL_PC". I tried this and worked when I hosted the mentioned maps.
Edit: I've fixed it, just removing each sound folder from the AddOns located in Server Management folder. The soundbanks don't need to be loaded here again.
