Replacing audio stream when switching devices

I’ve implemented a logic in the audio engine, that allows the Kadent DAW to switch the output device.
It was challenging because Mixer and MPSC consumers cannot be cloned. Finally I used Arc and Mutex in order to share the context with multiple threads.

let callback_ctx = Arc::new(Mutex::new(OutputCallbackContext {
        mixer,
        command_cons,
        midi_cons,
        vu_prod,
        pending_project: pending_arc,
    }));

I used try_lock instead of normal lock, which may block the thread, as you can see in the screenshot.
