# RemoveObject

Removes an audio object from the driver.

```
kern_return_t RemoveObject(IOUserAudioObject *in_object);
```

## Parameters

`in_object`

The [`IOUserAudioObjectID`](/documentation/AudioDriverKit/AudioDriverKit/IOUserAudioObjectID) to remove from the driver.

## Return Value

<doc://com.apple.documentation/documentation/DriverKit/kIOReturnSuccess> on success, or another value if an error occurs. For a list of error codes, see <doc://com.apple.documentation/documentation/DriverKit/error-codes>.

## Discussion

If the remove succeeds, the object’s reference count decrements by one. The caller should also call [`PropertiesChanged`](/documentation/AudioDriverKit/IOUserAudioDriver/PropertiesChanged) to notify the host of any changes.
