I know this is supposed to be fixed as of the latest update after looking at the changelog, but I can confirm that the current build of Stormfox on the workshop is muting/stopping triggerable soundscapes from working properly.

A map I've been testing that uses triggerable soundscapes for areas will work correctly without stormfox installed, but then will stop working whenever it is installed, I have tried the override soundscape option on and off both with the same result, and it happens both on a dedicated server and p2p games, without other addons that could be conflicting with it.

Normal soundscape entities seem to work fine though, with both with the override option on and off, only the triggerable soundscapes have this issue
