```

```

## Discussion

A read/write `UInt32` value. By default, the value of this property is `FALSE` (`0`).

This property can be used to modify the  [`kAudioSessionCategory_RecordAudio`](/documentation/AudioToolbox/kAudioSessionCategory_RecordAudio) or [`kAudioSessionCategory_PlayAndRecord`](/documentation/AudioToolbox/kAudioSessionCategory_PlayAndRecord) categories. Attempting to set this property to `TRUE` will fail for all other categories.

This property affects the [`kAudioSessionCategory_PlayAndRecord`](/documentation/AudioToolbox/kAudioSessionCategory_PlayAndRecord) category as follows: If the audio input to the device is coming from a Bluetooth headset, setting this property to `TRUE` results in audio output also going to the Bluetooth headset.
