QMediaPlayer doesn't work on Android 10

Devoo

Hi,
I created simple qt quick project to test QMediaPlayer.
For some reason it works perfectly on Windows but it is silent on Android.
I just changed main.cpp:

#include <QGuiApplication>
#include <QQmlApplicationEngine>

#include <QMediaPlayer>
#include <thread>
#include <QDebug>
#include <QtConcurrent>

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/qml/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl)
    {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    },
    Qt::QueuedConnection);
    engine.load(url);


    // Test
    QMediaPlayer* player;
    auto thread = QtConcurrent::run([&player]()
    {
        using namespace std::chrono_literals;
        qDebug() << "Hello waiter";
        std::this_thread::sleep_for(3s);

        // ...
        player = new QMediaPlayer();
        player->setMedia(QUrl("http://www.hochmuth.com/mp3/Vivaldi_Sonata_eminor_.mp3"));
        player->setVolume(50);
        player->play();

        qDebug() << "Player is playing now";

    });

    return app.exec();
}

and added multimedia to .pro file.

Logs:

What's wrong with this code?
