QSoundEffect change source hear both on Linux

When changing the source of a QSoundEffect I will hear the old and the new sound during the first play() and only the new sound in following play()s. I created a short test project that shows the effect for C++, but I found the same when using QML.

The output.wav shows the effect of issuing

mSoundEffect.setSource(QUrl::fromLocalFile(":/beep2.wav"));
mSoundEffect.play();

three times in a row. The first occasion is wrong the two others correct.

This only happens on Linux. I tried the code on my Moto G Android phone and everything works as expected
