# AudioHardwareServiceSetPropertyData(_:_:_:_:_:_:)

Asks a HAL audio object to change the value of a specified property.

## Declaration

```swift
func AudioHardwareServiceSetPropertyData(_ inObjectID: AudioObjectID, _ inAddress: UnsafePointer<AudioObjectPropertyAddress>!, _ inQualifierDataSize: UInt32, _ inQualifierData: UnsafeRawPointer!, _ inDataSize: UInt32, _ inData: UnsafeRawPointer!) -> OSStatus
```

## Parameters

- `inObjectID`: The HAL audio object to set a property value on.
- `inAddress`: The property to set.
- `inQualifierDataSize`: A UInt32 value indicating the size of the buffer pointed to by the inQualifierData parameter. Not all properties require qualification; in such a case you set this parameter to 0.
- `inQualifierData`: A buffer of data to be used in determining the value of the property being queried. Not all properties require qualification; in such a case you set this parameter to NULL.
- `inDataSize`: A UInt32 value indicating the size of the buffer pointed to by the inData parameter.
- `inData`: The buffer containing the data to be used as the new property value.

## Return Value

Return Value A result code.

## Discussion

Discussion The property should not be considered changed until the HAL has called your property listener callback. Many HAL audio object properties are changed asynchronously.
