Android - Getting audio to play through earpiece

Hi,

On iOS, starting the microphone routes sound through the earpiece speaker, and there's https://github.com/cbaltzer/UnitySpeakerFix to force sound back to the normal speaker.

On android the audio is not rerouted when activating the microphone, and I can't find any plugins to control the behaviour. If someone has done this and would be willing to share it i'd appreciate it.

thanks, Patrik
