No audio in iframe on Chrome Android

Problem Description

No audio in Chrome on android with iframe happens on C2 and C3. Works on all other browsers. It also happens with the iframes on Scirra arcade where no audio is heard on chrome for android.

My Chrome version is 61.0.3163.98

After looking into the console log on Chrome Android the error i'm getting is -

An AudioContext in a cross origin iframe must be created or resumed from a user gesture to enable audio output.

Ashley After searching online I found this -

The AudioContext.state will tell you if it's "running" or "suspended". If it's "suspended", call AudioContext.resume() from inside a user gesture, and it should start it up for you (without having to recreate state).

Is there anyway you could implement this in construct 2/3, my games really depends on audio

This should be fixed in the next builds of C2 and C3. We'll test it in the next release of C3 and if it doesn't cause any problems, we'll ship it with a C2 stable update soon after hopefully.
