Way to detect if audio is actually running on web

[crumblingstatue]

Audio context creation requires user input on modern web browsers.
When I call run_output_device, it seems to succeed even if there was no user input, but my provided closure isn't being called at all, and there is no audio output.
This was tested on Firefox.

In this case, I would like to know if the audio context creation actually failed due to no user input beforehand, so I can tell the user the audio context isn't running, and let them click a button to start it.

The docs explicitly states that you need to initialize the library after some action on your web-page. Here's a more detailed explanation. This behavior is enforced by web browsers and this is not an error to try to resume an audio context outside of a user interaction. It may be a good idea to add state fetching to the API of this library and use something like this on web.
