# RemoveClockDevice

Adds an audio clock device to the audio box.

```
kern_return_t RemoveClockDevice(IOUserAudioClockDevice *in_clock_device);
```

## Parameters

`in_clock_device`

The [`IOUserAudioClockDevice`](/documentation/AudioDriverKit/IOUserAudioClockDevice) to disassociate from the box.

## 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 removing the clock device succeeds, the clock device’s reference count decrements by one.
