Hello
So I installed a siren mod this morning and, despite following all the steps, the default siren sound didn't get replaced. Then I tried to rename the main siren sound file to SIREN_PA20A_WAIL, which is the default GTA siren for LSPD cars, but the siren became mute.
I don't have ELS, I don't know if that's the problem.
EDIT: I forgot to say that yelp and phaser do get replaced, but not wail.
