```

```

## Discussion

The value of this property is [`AVAudioSession.RenderingMode.notApplicable`](/documentation/AVFAudio/AVAudioSession/RenderingMode-swift.enum/notApplicable) in the following cases:

- The currently selected port isn’t of type [`carAudio`](/documentation/AVFAudio/AVAudioSession/Port/carAudio) or, in iOS 18 and later, [`airPlay`](/documentation/AVFAudio/AVAudioSession/Port/airPlay).
- Your app uses a playback API other than <doc://com.apple.documentation/documentation/AVFoundation/AVPlayer> or <doc://com.apple.documentation/documentation/AVFoundation/AVSampleBufferAudioRenderer>.
- Playback isn’t currently active.
- The audio session is inactive, muted, or not eligible for Now Playing.
