Possibility of playing sound only out of earpiece?

Hello,

I wanted to ask is there any way to specify the output when playing a sound file? I noticed that on iOS it plays out of both the earpiece and speaker. On some Android devices it only plays out of the speaker.

I would like for the sound to only play out of the earpiece. Is there is a specific place in the plugin that you are specifying the output natively?

Let me know and thank you!
