# init(devicePlacement:deviceCapabilities:primaryAudioSourceDeviceIdentifier:secondaryAudioSourceDeviceIdentifier:)

Creates an audio accessory configuration.

```
init(devicePlacement: AccessoryControlDevice.Placement? = nil, deviceCapabilities: AccessoryControlDevice.Capabilities, primaryAudioSourceDeviceIdentifier: Data? = nil, secondaryAudioSourceDeviceIdentifier: Data? = nil)
```

## Parameters

`devicePlacement`

The current placement state of the accessory.

`deviceCapabilities`

The capabilities the accessory supports.

`primaryAudioSourceDeviceIdentifier`

The Bluetooth address of the primary audio source.

`secondaryAudioSourceDeviceIdentifier`

The Bluetooth address of secondary audio source.

## Discussion

For example, the following code creates a configuration for a device that’s not being worn and is using Bluetooth address `0x12356789ABC` as its primary audio source:

```swift
let configuration = Configuration(
    devicePlacement: .offHead,
    deviceCapabilities: [.placement, .audioSwitching],
    primaryAudioSourceDeviceIdentifier: Data([0x12, 0x34, 0x56, 0x78, 0x9A, 0xBC]),
)
```
