Setting AudioSpeakerMode.Mono has no effect on Android devices

Setting the configuration speakerMode = AudioSpeakerMode.Mono on Android has no affect on audio being played back. Other platforms like iOS and windows appear to work correctly and playback in Mono.

Was suggest to create new bug for further investigation:(slack thread for reference)

Sample of code being used: 

AudioConfiguration audioConfig = AudioSettings.GetConfiguration();
audioConfig.speakerMode = AudioSpeakerMode.Mono;
AudioSettings.Reset(audioConfig);
