Gets the output speaker configuration of the specified output. Call this function to get the speaker configuration of the output (which may not correspond to the physical output format of the platform, in the case of downmixing provided by the platform itself). You may initialize the sound engine with a user-specified configuration, but the resulting configuration is determined by the sound engine, based on the platform, output type and platform settings (for e.g. system menu or control panel option). If the speaker configuration of the output is object-based, the speaker configuration of the main mix is returned. To query more information on object-based output devices, see AK::SoundEngine::GetOutputDeviceConfiguration.
It is recommended to call GetSpeakerConfiguration anytime after receiving a callback from RegisterAudioDeviceStatusCallback to know if the channel configuration has changed.
