Audio stops unexpectedly

[Abdeljalil]

i'm playing an audio file (.ogv) with MediaPlayer and Audio components and i set audio to loop infinitly, but after sometime the audio stops playing
the code:
@
MediaPlayer
{
id : sound
source: "qrc:///resources/audio.ogv"
autoLoad: true
autoPlay: true
loops: Audio.Infinite
property bool isPlaying: true

}

Audio
{
    source: sound
}
