Only buzzing sound while playing wav/mp3 files through QAudioOutput

[TheIndependentAquarius]

I realised that the wav file which I was running was not actually a wav file. It was a mpeg compressed file with the extension wav.
With a real wav file, this example works fine.

I know it has been long time.
Would someone tell me how to play wav file with QAudioOutput ?
File format is wrong i think but i do not know how to fix it.
I am using Qt 4.8 and having same buzz problem.

thanx in advance..
