Comment 8 for bug 1397142

I think I have the same problem with Sony SBH20, Ubuntu 15.04, kernel 4.0.4

Device is paired and bluetooth buttons detectable in "System Setings" -> "Keyboard" -> "Shortcuts" -> "Sound and Media"

* Previous Track detected as "Audio previous" and working as expected in all apps
* Next track detectable as "Audio next" and working as expected in all apps

* Play (or play/pause) detectable as "Audio play", but does not stop resume playback in all apps

Working apps:
1. Totem Movie Player
2. Spotify, but only if you click twice

Not working apps:
1. Pithos (pandora app for linux)
2. Chrome or FireFox (this is maybe app specific problem)
3. Rhythmbox

I would like to add that all apps (except chrome and firefox) are working with the keyboard pause/resume media key.
Question: who knows the flow of key events, please suggest how to debug this problem?

Here is output from "xev" for bluetooth pause/resume key
