详细描述

AttenuationModelLinear must be defined inside AudioEngine or be added to it using AudioEngine.addAttenuationModel() if AttenuationModelLinear is created dynamically.

Rectangle {
    color:"white"
    width: 300
    height: 500
    AudioEngine {
        id:audioengine
        AttenuationModelLinear {
           name:"linear"
           start: 20
           end: 180
        }
        AudioSample {
            name:"explosion"
            source: "explosion-02.wav"
        }
        Sound {
            name:"explosion"
            attenuationModel: "linear"
            PlayVariation {
                sample:"explosion"
            }
