Setting default audio output before making connection

[mjcctech]

Short version:
I would like to set up which output device (earpiece or speaker) should be used. I want to set it up before making connection. I tried two methods selectAudioOutput and turnOnSpeaker. But at the beginning earpiece is always used. After audio connection is established I can switch between them using selectAudioOutput method.

Longer version:
I work on voice application. User can call to other user by clicking button. Establishing webrtc audio connection takes some time and sound file is playing during that process. There is additional button to switch audio output between earpiece and speaker. It is possible to switch audio output even during making connection - audio from sound file change output accordingly.
And here is problem because audio from webrtc starts playing always on earpiece. Executing cordova.plugins.iosrtc.selectAudioOutput('speaker') has effect only on active audio stream.
