1. Create `AVAudioPlayerNode`

2. Connect it to `AVAudioEngine`'s `mainMixer` node 

3. Start the engine and start the player

4. Connect any effect (e.g. reverb) to player and engine's main mixer 

5. Expected: Player keeps playing and sound is affected by new effect

6. Actual: Player is stopped, which breaks the audio flow
