Why does QSoundEffect play sounds poorly unlike QMediaPlayer?

[NightShadeI]

I'm trying to play a very short sound (definitely less than a second , maybe 0.2 seconds)

I notice the sound is clear and crisp from QMediaPlayer, but not from QSoundEffect in Qt6 using C++

The start or end of the sound gets cutoff in QSoundEffect which sounds counter-intuitive given its optimised for things like this

I notice many applications to play audio files have this issue, but some play it really smoothly just like QMediaPlayer

My operating system is Windows 10

Please show your code.

Alright will share the code here, hadn't initially intended to provide it because I don't think it will be useful , and more fishing for an answer as to why the two are giving different results. Also I cannot provide the wav file by law, nonetheless, here is the relavent code:

int main(int aArgc, char *aArgv[]) {
    QApplication myApplication{aArgc, aArgv};

    QMediaPlayer* myMediaPlayer = new QMediaPlayer;
    myMediaPlayer->setSource(QUrl::fromLocalFile("path/to/file.wav"));
    
    QAudioOutput* myMediaAudioOutput = new QAudioOutput;
    myMediaAudioOutput->setVolume(1.f);
    myMediaPlayer->setAudioOutput(myMediaAudioOutput);
    
    QSoundEffect* myEffectPlayer = new QSoundEffect{};
    myEffectPlayer->setSource(QUrl::fromLocalFile("path/to/file.wav"));
    myEffectPlayer->setVolume(1.f);
    myEffectPlayer->setLoopCount(1);

    // myEffectPlayer->play();
    myMediaPlayer->play();

    return myApplication.exec();
}

@NightShadeI Ok, th code looks good and I don't see an obvious error. Please create a bug report and post the bug number here.
