Description

When playing a video on a FireTV stick, the sound is not audible.
When trying to select "HDMI" as audio output, "Output device not set" is printed to the console.
The reason for this is that QtAudioDeviceManager::setAudioOutput doesn't support AudioDeviceInfo.TYPE_HDMI.

Example code:
Since the ffmpeg backend is currently unable to play HLS steams (QTBUG-118168), the native backend is used:

qputenv("QT_MEDIA_BACKEND", "android");

import QtQuick
import QtQuick.Controls
import QtMultimedia

ApplicationWindow {
    visible: true

    MediaDevices {
        id: devices
    }

    MediaPlayer {
        id: mediaplayer
        source: "https://hls-master.video.pareygo.de/1adbe4a13e6f65fc282ce1ceef22117c.m3u8"
        audioOutput: AudioOutput {
            Component.onCompleted: {
                for(var audioDevice in devices.audioOutputs)
                {
                    if(devices.audioOutputs[audioDevice].description.startsWith("HDMI"))
                    {
                        device = devices.audioOutputs[audioDevice]
                    }
                }
            }}
        videoOutput: videoOutput
    }

    VideoOutput {
        id: videoOutput
        anchors.fill: parent
    }

    Component.onCompleted: mediaplayer.play()
}
