SoundEffect in QML for iOS

[franky]

Hi all,

I'm using Qt 5.12 and in the following project, I want to use a simple SoundEffect in QML to play a sound on iOS:

In the .pro file, I only added "multimedia" to the end of "QT += quick" and also the code block below at the end:

ios {
    APP_Sounds.files = $$PWD/sounds/kimya.mp3
    APP_Sounds.path = sounds
    QMAKE_BUNDLE_DATA += APP_Sounds
}

ios {
    APP_Sounds.files = $$PWD/sounds/kimya.mp3
    APP_Sounds.path = sounds
    QMAKE_BUNDLE_DATA += APP_Sounds
}

The main.cpp file is intact, and without changes.

And, this is main.qml file:

import QtQuick 2.12
import QtQuick.Window 2.12
import QtMultimedia 5.12
 
Window {
    visible: true
    width: 640; height: 480
    title: qsTr("Hello World")
 
    Rectangle {
        width: 100; height: 100
        color: "green"
        anchors.centerIn: parent
 
        MouseArea {
            anchors.fill: parent
            onClicked: playExplosion.play()
        }
    }
 
     SoundEffect {
        id: playExplosion
        source: "file:///Users/Me/QML/soundTest/soundTest/sounds/kimya.mp3"
    }
}

import QtQuick 2.12
import QtQuick.Window 2.12
import QtMultimedia 5.12

Window {
    visible: true
    width: 640; height: 480
    title: qsTr("Hello World")

    Rectangle {
        width: 100; height: 100
        color: "green"
        anchors.centerIn: parent

        MouseArea {
            anchors.fill: parent
            onClicked: playExplosion.play()
        }
    }

     SoundEffect {
        id: playExplosion
        source: "file:///Users/Me/QML/soundTest/soundTest/sounds/kimya.mp3"
    }
}

But the problem is that, no sound played on iOS.
What part of this code is wrong, please?

Have you checked the SoundEffect's status property?

Is it "Ready" when you call play()?

I used this code for the onClicked: { part in main.qml:

...
onClicked: {
                if (playExplosion.Ready)
                playExplosion.play()
                else console.log("Not ready")
            }
...

...
onClicked: {
                if (playExplosion.Ready)
                playExplosion.play()
                else console.log("Not ready")
            }
...

It showed these errors when tested on Mac (Clang 64_bit kit):
QSoundEffect(qaudio): Error decoding source
qml: Not ready

And when I replace the .mp3 file with a .wav file, the first error vanishes but the error: "qml: Not Ready" still appears when I click the green rectangle.

How to make it ready, please?
Shouldn't I change the .pro or main.cpp file?

[anda_skoa]

"Ready" is just a value, you need to check if the "status" property contains that value

if (playExplosion.status === SoundEffect.Ready) {
} else {
    console.log("SoundEffect status not Ready but " + playExplosion.status)
}

if (playExplosion.status === SoundEffect.Ready) {
} else {
    console.log("SoundEffect status not Ready but " + playExplosion.status)
}

Thanks so much. The problem is solved. Apparently iDevices (especially iPhones) play only .wav files within apps).
