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

Creates a new device configuration with spatial audio support.

## Declaration

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

## Parameters

- `devicePlacement`: The current placement state (e.g., .offHead, .onHead, .inEar) - only applicable with .placement capability
- `deviceCapabilities`: The capabilities supported by the device (e.g., [.placement, .audioSpatialization])
- `primaryAudioSourceDeviceIdentifier`: Bluetooth address of the primary audio source (only applicable with .audioSwitching capability)
- `secondaryAudioSourceDeviceIdentifier`: Bluetooth address of secondary audio source (only applicable with .audioSwitching capability)
- `spatialExtensionDescription`: The audio component description for the spatial audio rendering extension (only applicable with .audioSpatialization capability)
