# useApplicationAudioSession

A Boolean value that indicates whether the movie player should use the app’s audio session.

## Declaration

```swift
var useApplicationAudioSession: Bool { get set }
```

## Discussion

Discussion The default value of this property is true. Setting this property to false causes the movie player to use a system-supplied audio session with a non-mixable playback category. When this property is true, the movie player shares the app’s audio session. This give you control over how the movie player content interacts with your audio and with audio from other apps, such as the iPod. For important guidance on using this feature, see Audio Session Programming Guide in Audio Session Programming Guide. Changing the value of this property does not affect the currently playing movie. For the new setting to take effect, you must stop playback and then start it again. Special considerations In iOS 3.1 and earlier, a movie player always uses a system-supplied audio session. To obtain that same behavior in iOS 3.2 and newer, you must set this property’s value to false.
