That is a problem with your audio files. Perhaps you’ve modified RESIDENT.rpf or so?

yes i have. but SA’F has modified sirens and they dont have a problem

SA’F

Haven’t got a clue about what you’re talking about.

Ok, they have modified different files clearly. This issue can’t be repro’d using a clean RESIDENT.rpf file.

so im guessing there is no fix to it? unless i modify the firetrucks airhorn

The fix is to not modify the RESIDENT.rpf file in the first place.
