# isAutoShutdownEnabled

A Boolean value that indicates whether autoshutdown is in an enabled state.

## Declaration

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

## Discussion

Discussion If autoshutdown is in an enabled state, the engine can start and stop the audio hardware dynamically to conserve power. In watchOS, autoshutdown is always in an enabled state. For other platforms, it’s in a disabled state by default.
