What does the error say?

I wonder if you combined the scripts if it would work? What's line 53 in your description.ext? If you have notepad++ it will tell you your lines.

class CfgSounds {
	sounds[] = {prayer};
	class prayer {
		name = "prayer";
		sound[] = {"CalltoPrayer\sounds\prayer.ogg", db+1, 1};
		titles[] = {};
	};
	sounds[] = {Vent,Vent2,Para};	
	// ATM AirDrop
	class Vent {name="Vent";sound[]={"ATM_airdrop\data\Vent.ogg",db-11,1.0};titles[] = {};};
	class Vent2 {name="Vent2";sound[]={"ATM_airdrop\data\Vent2.ogg",db-11,1.0};titles[] = {};};
	class Para {name ="Para";sound[]={"ATM_airdrop\data\parachute.ogg",db-11,1.0};titles[] = {};};	
};

Or something like that? Long shot but I'd do a backup and try it until a scripter gets in here. :)

Yeah, for missions, you cannot double-define config entries such as CfgSounds and CfgFunctions. You will have to combine the entries.

class CfgSounds {
	sounds[] = {prayer,Vent,Vent2,Para};

	//-- Call to prayer
	class prayer {
		name = "prayer";
		sound[] = {"CalltoPrayer\sounds\prayer.ogg", db+1, 1};
		titles[] = {};
	};

	// ATM AirDrop
	class Vent {name="Vent";sound[]={"ATM_airdrop\data\Vent.ogg",db-11,1.0};titles[] = {};};
	class Vent2 {name="Vent2";sound[]={"ATM_airdrop\data\Vent2.ogg",db-11,1.0};titles[] = {};};
	class Para {name ="Para";sound[]={"ATM_airdrop\data\parachute.ogg",db-11,1.0};titles[] = {};};	
};

Ah! Cool. So not just sort of combined but REALLY combined, I see. This doesn't bode well for me to getting Autigergrad's sound pack working with the Call to Prayer script. :(

I'll have to ask AA to share his description.ext. :)

It works fine.

My sounds are defined as sfx sounds, Call to prayer is defined as actual "sound", two completely different categories.

Look at the Description.ext I provided in my ambient sounds pack. all you have to do is copy and paste the description.ext with the call to Prayer add on into that same description.ext so you'll have both the cfg SFX and cfg Sounds in one description.ext. That's it. You'll also want to make sure the actual sounds are in the mission as well of course.

Oh ok. So in this instance I can have their respective entries written individually in the description.ext I take it then? That's good. The easier the better. :)

My sounds are 3D sounds...they are not Cfg Sounds. I'm not staring at my description.ext right now but I think it's CFG sfx or something like that.

You're just pasting on the Cfg sounds portion for the call to prayer to the Cfg SFX. Should work fine.

If it looks different than this:

class CfgSounds {
	sounds[] = {prayer};
	class prayer {
		name = "prayer";
		sound[] = {"CalltoPrayer\sounds\prayer.ogg", db+1, 1};
		titles[] = {};
	};

*Your sounds pack stuff here

So like literally just placing them back to back like any other description.ext entry, could you post your description.ext back here?

Correct. Back to back

Replace your CallToPrayer\init.sqf file with this code

if !(isServer) exitWith {};

_CalltoPrayerDebug = false;
_functions = execVM "CallToPrayer\functions.sqf";
waitUntil {scriptDone _functions};

//-- Get cities
_cities = [] call CalltoPrayer_fnc_getCities;

CalltoPrayerLoudspeakers = [];
{
	_cityPos = _x select 0;

	{
		_pole = "Land_Loudspeakers_F" createVehicle (getPosATL _x);
		CalltoPrayerLoudspeakers pushBack _pole;

		if (_CalltoPrayerDebug) then {
			_n = format["%1", floor (random 1000)];
			_marker = createMarker [_n, _spawnPos];
			_marker setMarkerShape "ICON";
			_marker setMarkerType "mil_dot";
			_marker setMarkerText "CTP loudspeaker";
		};
	} foreach (nearestobjects [_cityPos, INS_CTPLOCATIONS, 600]);
} forEach _cities;

[] call CalltoPrayer_fnc_prayerLoop;

And then in your standard init.sqf (one that is executed automatically in each mission), simply define
INS_CTPLOCATIONS = ["CUP_A2_minaret_ep1"];

Damn, just forgot FATA has no cities defined.. I'll make another modification real quick

Ok, then just replace the function you posted with this

CalltoPrayer_fnc_getCities = {
	private ["_locations","_cityTypes","_randomLoc","_x","_cities"];
	_cities = [];

	_locations = configfile >> "CfgWorlds" >> worldName >> "Names";
	_cityTypes = ["NameVillage","NameCity","NameCityCapital","NameLocal"];

	for "_x" from 0 to (count _locations - 1) do {
		_randomLoc = _locations select _x;

		private["_cityPos","_cityType"];
		_cityPos = getArray(_randomLoc >> "position");
		_cityType = getText(_randomLoc >> "type");
		if (_cityType in _cityTypes) then {
			_cities pushback [_cityPos];
		};
	};

	{_cities pushback (getmarkerpos _x)} foreach INS_CTPMARKERS;
	_cities;
};

Then place markers (icons, not rectangles/ellipses) on each of the cities that you want CTP to look for nearby INS_CTPLOCATIONS. After that, go back to your init.sqf where you defined INS_CTPLOCATIONS and define

INS_CTPMARKERS = ["markername1","markername2","markername3"];

Remember to put quotes around each marker name and separate them with a comma.

Another quick thing to keep in mind, define these INS_x variables BEFORE you call the initialization function.

So, to be safe, define these variables at the very top of your init.sqf
