There is a critical issue where the audio is only coming through the speaker. Additionally, Hardware.instance.canSwitchSpeakerphone is always false, and Hardware.instance.setSpeakerphoneOn(false) has no effect on iOS.
Similarly, On Android, setting room.setAudioOutputDevice('earpiece') also has no effect.
This functionality used to work in version 2.1.3

To Reproduce
This issue is easy to reproduce by running the example app and attempting to switch to the earpiece on Android. On iOS, the button to switch to the speaker is disabled.

Expected behavior
Should be able to switch between earpiece & speaker.
