So, I thought I had it until I realised the Sheriffs SUV has different sirens to the other Police Cars, but I tried it again, did that same update and didn't work. So not exactly sure now.
No it more of isn't working. It still has the default sirens, GTA V's original ones. I goto where handing.meta is in OpenIV and replace it with the one in the file, I believe that is what you do, correct? If not I haven't installed it properly. If not a quick tutorial or images would be helpful. But with the whole update thing, as soon as I try to open the game it has a 106MB update it does, and I'm not sure if that is re-doing the sirens or it likes to update every time. One of them is the issue aha.
So when I install, it works. But when I launch the game, the game does an update and then once I can play it, the sounds don't work. This has happened twice now, I have redownloaded the pack once now. Still no effect, I think I saw something about disabling your Antivirus for the time? or something. Atleast until you get in game. Any idea?
