The behavior can be triggered with the toggleAudioOnly action, which is currently fired with a button. The following aspects of the conference will change when in audio only mode: - local video is muted - last N is set to 0 (effectively muting remote video) - full-screen mode is exited - audio mode is set to "audio chat" (default output is the earpiece) - the wake lock is disengaged One aspect not handled in this patch is disabling the video mute button while in audio only mode. The user should not be able to turn back video on in that case.
