Turns out that it seems that the event is not fired on boot. I can't debug more, I don't have time. See HeadphoneSwitchObserver class, Notify method in dom/system/gonk/AudioManager.cpp.

With the patch attached, I see the event being triggered, but statusbar not catching it on boot. I can't help more.

@autonome According to lissyx, someone that knows mozChromeEvent will be needed for fixing this bug.

is there gaia work required, or will the platform fix address the issue completely?

No, the platform fix is needed I think, since we cannot have headphones status in gaia without having the event triggered at boot time, which is what the fix I sent does. But somehow, this event does not make it to the statusbar. I suspect some race condition between this boot-time event and the handler in gaia which is not yet installed. But I'm not a master of events, and I can't dig in right now, so better to let someone at ease with mozChromeEvent lifecycle look at this.

Is this still an issue? Works for me on my Nexus S.
