AudioObjectSetPropertyData App freezes

      let volumePropertyAddress = AudioObjectPropertyAddress(
        mSelector: kAudioHardwareServiceDeviceProperty_VirtualMainVolume,
        mScope: kAudioDevicePropertyScopeOutput,
        mElement: kAudioObjectPropertyElementMaster
      )

     let status = AudioObjectSetPropertyData(deviceId, &theAddress, 0, nil, size, &theValue)

Then App freezes. Is it not possible to call the AudioObjectSetPropertyData method on the main thread
