## AudioManager
Implements audio volume and audio device management. Before calling any API in **AudioManager**, you must use [getAudioManager](#audiogetaudiomanager) to create an **AudioManager** instance.
> You are advised to use [on('volumeChange')](#onvolumechange9) in **AudioVolumeManager**.
> This API is supported since API version 8 and deprecated since API version 9. You are advised to use [on('volumeChange')](#onvolumechange9) in **AudioVolumeManager**.
Checks whether the fixed volume mode is enabled. When the fixed volume mode is enabled, the volume cannot be adjusted. This API returns the result synchronously.
| boolean | Returns the status of the fixed volume mode. The value **true** means that the fixed volume mode is enabled, and **false** means the opposite.|

Immersive window: System windows such as the status bar and navigation bar are controlled in such a way that they are unobtrusive and natural looking in the entire screen, thereby engaging users more deeply with the content displayed.
The immersive window feature is valid only when the main window of an application is displayed in full-screen mode. It does not apply to a main window in free window mode or a subwindow (for example, a dialog box or a floating window).

- Method 1: When the main window of the application is a full-screen window, call **setWindowSystemBarEnable** to hide the status bar and navigation bar.
- Method 2: Call **setWindowLayoutFullScreen** to enable the full-screen mode for the main window layout. Call **setSystemProperties** to set the opacity, background color, text color, and highlighted icon of the status bar and navigation bar to ensure that their display effect is consistent with that of the main window.
