I tried this exactly and it didnt work: https://github.com/World-Control-Team/World-Control/wiki/Adding-Custom-Sounds-to-the-Howler-Alarm

Please help what should i do? Is it no longer possible?

For others: there's mod called energy control, it is same like word control but more updated and it works correctly.

it also has a lot of compat for other mods

You probably did something wrong. Please share your sounds.json file, since that's usually what people mess up with.

{
"alarm-nuclearalarmsiren": {"category": "master","sounds": [{"name": "worldcontrol:alarm-nuclearalarmsiren","stream": true}]}
}

file was modified in WCalarms/assets/worldcontrol/sounds.json

I think the JSON file is correct. Did you add the .ogg file and add the custom alarm to the config while changing UseCustomSounds to true? Please show me your config file.

Yes i added sound file called alarm-nuclearalarmsiren.ogg

Yes i added true to usecustomsounds. I cant copy the file here cuz i am not on pc right now

Configuration file

general {
I:SMPmaxAlarmRange=256
I:alarmRange=64
S:howlerAlarmSounds <
default
sci-fi
nuclearalarmsiren
>
I:maxAlarmRange=128
I:remoteMonitorPowerUseIC2=1
I:ticksBetweenHowlerSound=2
B:useCustomSounds=true
}

Is that the exact config file? I would try to delete it to regenerate it, I think it might be the issue. And then add nuclearalarmsiren.

Yes it gives me this config file everytime i delete it. Is it a bug? I downloaded latest version of worldcontrol

I don't think so. I can't see what's wrong but other people have gotten their alarms working.

So what should i do?

Idk. Do you wanna see if I missed something? @dmf444
