Something strange happend with soundinterface since var. 19.8 has been released.
Playing sound automatically on android seems to be impossible (it's possible if you click anyhing or put playsound into your context menu). I tested it also on plugin's page:

Sound doesn't starts on my Samsung S6 (for Gear VR) with Chrome. Does anyone noticed such problems? Could you test it?
I tested it on Samsung S6, Android 5.1.1, Chrome 56.0
PS.
I've just noticed this post:

It's just the same problem: On Android sounds starts only on user's interaction.
