[Android] QSound problems playing sounds

I created a Qt quick project , which use QSound play a sound,
Now the sound files into the resources qrc file.
calling the following code

  QSound sound(":sound/testsound.mp3");
          sound.play();
  

only beep once , did not play a sound file .
I checked the path is not wrong , how to modify how it can play a sound ? ?
------ Solution ---------------------------------------- ----
QSound does not support resource files

only play files on disk .
------ Solution ---------------------------------------- ----


should support it.

problem here is QSound does not support mp3 format file playback .
document is described:
Microsoft Windows The underlying multimedia system is used; only WAVE format sound files are supported.
X11 The Network Audio System is used if available, otherwise all operations work silently. NAS supports WAVE and AU files.
Mac OS X NSSound is used. All formats that NSSound supports, including QuickTime formats, are supported by Qt for Mac OS ; X.
Qt for Embedded Linux A built-in mixing sound server is used, accessing / dev / dsp directly. Only the WAVE format is supported.
Symbian CMdaAudioPlayerUtility is used. All formats that Symbian OS or devices support are supported also by Qt.

landlord can try to sound resource converted to wav format to use. If you must use the mp3 on the use of other types of bars , QSound not do
