AudioContext cross domain blocking in iframe

Though I only play audio in response to clicks, I initialize the AudioContext and buffers and such when the script loads.

In mobile Chrome 57.0.2987.132 the console shows the following warning when loaded from an iframe:

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

For audio to work I recreate the AudioContext on first click. Is there a way to simply activate the existing AudioContext on the first click? Also can I detect whether the audio is currently blocked?

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).
