Background staysActiveInBackground argument for Audio.setAudioModeAsync(mode)

The playlist does not keep playing in the background even after changing the Audio Mode.

```
Audio.setAudioModeAsync({
allowsRecordingIOS: false,
staysActiveInBackground: true, <--- Changed this
playsInSilentModeIOS: true,
shouldDuckAndroid: true,
interruptionModeAndroid: InterruptionModeAndroid.DoNotMix,
playThroughEarpieceAndroid: false
});
```

I cloned the project, changed that value and that's all I did.

Is there anything extra that needs to be done in this example to have it work in the background?

Thank you!
