Earphone button not working?

[uzanto]

I'm using a BQ Aquaris E4.5 and I'm not able to operate the earphone button to pause/play the songs or answer a call.

Is that button in the mic area that use to allow answer calls, play/stop music, etc.

Now that I remember it seems to me that it works when answering calls, but not for the music player.

Is it working for anyone?

There is an older bug issue in LP. The signalling is inband and not compatible with BQ.

Thank you for answer, do you know why is not compatible with BQ E4.5? on Android it worked properly.

Someone knows how the system reads the button presses? I found some information about that It's about voltage reading but I don't know if is needed a special hardware to do it.

It doesn't work on the OnePlus One either, even though it works on the OPO in android.

I can hangup a call, but I have no control on player, I think is working but not implemented properly, if someone finds information on how the system works that puts it here because I'm interested.

Here what I get from dbus-monitor while clicking the play/pause button:
