    Description

      Here is a Qt warning on changing audio input in standard Audio Source example - Examples/<Qt Version>/multimedia/audiosource/

      QIODevice::write (AudioInfo): device not open

      I suppose it doesn't depend on the platform or multimedia backend, but I reproduce it
      stably at least on macOS 14.3.1, with the next steps:

      1. Build and run Audio Source example
      2. Try to switch audio input, e.g. from built-in "MacBook Pro Microphone" to any other available device (like "ZoomAudioDevice" or "AirPods") or vice-versa.


      3. Observe the debug output.
