I attached the sources of a console app that plays a wav sound specified as an argument, see SoundTest.zip.

It connects to QAudioSink::stateChanged signal, calls QAudioSink::start and when it receives QAudio::IdleState it calls QAudioSink::start again.

On Windows and Android this results in an infinite loop, but on MacOS and iOS it is not, but the sound is played only once.

In my real-life app (not in the example) something goes wrong after an attempt to loop a sound in this way on MacOS/iOS and other sounds stops playing.

I tried to call QAudioSink::start with QTimer::singleShot, but it did not help.

Is this a bug or something that is not supported or probably used in a wrong way?

I also attached a wav sound, so the app can be started as

SoundTest sound.wav
