Using QtMultimedia - SoundEffect: Sounds of duration 20 or 50 ms do not play at all on my Android device, but 100 ms duration works. Did not figure out exactly where the cutoff limit is as I suspect that can be device or OS-version specific anyway. The two attached wave files are identical except the longer one has 50 ms of silence added to the end.

If this is a android system limitation then it should at least be documented under platform notes.

Tested using the following code:

import QtQuick 2.2
import QtMultimedia 5.0

Rectangle {
SoundEffect

{ id: testSound source: "qrc:///qml/50ms-doesntwork.wav" }

MouseArea {
anchors.fill: parent
onClicked:

{ console.log("playing!"); testSound.play(); }

}
}
