# Audio interface

Methods for controlling audio.

## Methods

[`isEnabled(): boolean`](https://developers.google.com/gamesnacks/developer/sdk/isenabled)   

Determines if game sound should be audible at this instant. **Required**

[`subscribe(callback: (isEnabled: boolean) => void): void`](https://developers.google.com/gamesnacks/developer/sdk/subscribe)   

Subscribes to changes to isEnabled.

## Requirements

- Your game **should not** show an overall mute button and should instead rely on the GameSnacks platform control for this.
- Your game **may** have separate granular audio controls in the game, such as for background music or sound effects, but it **must** still follow these requirements.
