<![CDATA[QSoundEffect not working in Qt 6.4.2 windows 10]]>Hi Guys i would like to play a soundeffect with the QSoundEffect but when i tried in this way:

QSoundEffect *soundEffect = new QSoundEffect();
soundEffect->setSource(QUrl("D:/QtProjectver200/Android_alarm/RES/alligator3.wav"));
soundEffect->setLoopCount(QSoundEffect::Infinite);
soundEffect->setVolume(50);
soundEffect->play();

And the audio is not playing. The error what the Qt write out:
QSoundEffect(qaudio): Error decoding source d:/QtProjectver200/Android_alarm/RES/alligator3.wav

Thanks for your help!

  • Yes the QFile::exists() returns true. I tried this way now (the file is in the build folder):
    effect.setSource(QUrl::fromLocalFile("engine.wav"));
    effect.setLoopCount(QSoundEffect::Infinite);
    effect.setVolume(0.25f);
    effect.play();

The new error is: qt.multimedia.audiooutput: Failed to set up resampler

  • Necessary decoder? I don't know what it is, I didn't add anything other than the main QT. I gave to add some decoder?
  • Yes I tried with some different paths and i tried with .OGG file too.

  • Make sure that is the correct path: if it is not QSoundEffect still gives this (somewhat misleading) error message. Use e.g. QFile::exists() to verify.
  • I don't know how this works on Windows, but do you have the necessary decoder for .wav files?
  • have you tried with another file in a different path? Have you tried with something other than a .wav file?
