## Detailed Description

The audioDevice value type describes the properties of an audio device that is connected to the system.

The audioDevice instance retains its properties throughout its lifetime, even if the corresponding physical device is disconnected or its settings are modified. To keep track of updated properties, the user should load new instances of audioDevice from MediaDevices when the relevant signals are fired.

The list of audio input or output devices can be queried from the MediaDevices type. To select a certain audio device for input or output set it as the device on AudioInput or AudioOutput.

     MediaPlayer {
         audioOutput: AudioOutput {
             device: mediaDevices.defaultAudioOutput
         }
     }
     MediaDevices {
         id: mediaDevices
     }
