Thanks Chinmay and Chris,

What’s the difference between the mediacapture-output API and the Audio Output Devices API proposal? Are they the same thing? If this is the right API to consider this signal in, what should the next step be? Should I create a proposal and send it to the editors? Is there a mailing list where this API is discussed?

Many thanks,

Seems like it would need to be like Android's plugged event - http://developer.android.com/reference/android/media/AudioManager.html#ACTION_HEADSET_PLUG - on the AudioContext, but it would need to be clear that it's not always going to trigger.

It seems somewhat related to the discussion of the Audio Output Devices API, but I would appreciate some thoughts/advice from the more experienced amongst you. Is it feasible to create an API call that would tell you if headphones are connected (provided that the underlying system can know obviously) and if so where should this request be directed?
