int32_t SetLoudspeakerStatus(bool enable) int32_t GetLoudspeakerStatus(bool* enabled) const These APIs are only implemented on iOS and they do not belong in the native audio layer since the client can achieve the same functionality by using the shared audio session in sdk/objc/Framework/Headers/WebRTC/RTCAudioSession.h. It also gives the client a better flexibility in how the audio routing is done.
