# init

Initializes an instance of the audio object base class.

```
virtual bool init(IOUserAudioDriver *in_audio_driver);
```

## Parameters

`in_audio_driver`

The [`IOUserAudioDriver`](/documentation/AudioDriverKit/IOUserAudioDriver) that owns this object.

## Return Value

A Boolean value that indicates the result of initialization: `true` if initialization succeeded, `false` otherwise.

## Discussion

Always pass in the [`IOUserAudioDriver`](/documentation/AudioDriverKit/IOUserAudioDriver). The no-arg initializer, [`init`](/documentation/AudioDriverKit/IOUserAudioObject/init-26qwx), always returns `false`.
