ERROR: 180: EXCEPTION thrown ('dev!'): - and ERROR:> aqsrv> 70: Exception caught in (null) - Error -1

问题

every time I call my function to use .wav files I get these errors:

ERROR: 180: EXCEPTION thrown ('dev!'): -

and

ERROR:> aqsrv> 70: Exception caught in (null) - Error -1

it always happens in the line of play().

It only happens in IOS - on android it runs well.

Function:

function sonido() {
    var cont=0;
    //console.log(arregloDetalles[cont].tVelocidad);
    var intervalo=setInterval(function() {
        if(bnaddetener==1){
            clearInterval(intervalo);
        }           
        if(arregloDetalles[cont].click_clack==1) {
            soundclick.play();

        } else {
            soundclack.play();
            console.log("Clack");
        }
        cont++;
        if(cont==arregloDetalles.length) {
            banderaclick=1;
            cont=0;
        }
    } ,arregloDetalles[cont].tVelocidad);
}

declaration of .wav files:

var soundclick = Titanium.Media.createSound({
        url:'/sonidos/beep-8.wav',
        preload:true
});
soundclick.addEventListener('complete', function(e) { soundclick.release(); });

var soundclack = Titanium.Media.createSound({
        url:'/sonidos/beep-7.wav',
        preload:true
});
soundclack.addEventListener('complete', function(e) { soundclack.release(); });
