Then I decided to give a different ENB a try - it was this ENB that I tried to download the second time time. Installed some weapons, weapon sounds, all worked well, police sirens still working. This time I installed the same mods from that video, all worked well. Pressing the horn key to turn on sirens doesn't work either.Īfter messing around for a bit, I couldn't get them to work again and re-installed GTA 4. Installed an ENB (iCEnhancer Natural) to test it out, it didn't work (had a black screen issue which I found out how to resolve), and once I removed the ENB files, I noticed that police cars no longer have the police horn, and instead have the default horn (I think it's the taxi horn). I installed all the mods in this video (downgrader, ZolikaPatch & GTA Connected), and it all worked well when my game was default.

How could a bunch of visual changes (legit just replaced the timecyc and visualSettings files) make my police cars' sirens suddenly not work *at all*? So obviously, just by the title you can see that this issue is very odd and doesn't seem related at all.
