[Bug 1397142] Re: Sony SRS-BTM8 play/pause key not fully effective in Rhythmbox or Banshee
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

Title:
Sony SRS-BTM8 play/pause key not fully effective in Rhythmbox or
Banshee
Status in unity-settings-daemon package in Ubuntu:
Confirmed
Bug description:
I have a Sony SRS-BTM8 Bluetooth speaker, and its audio side works
fairly well with Ubuntu. It also has a play/pause button and that
doesn't work so well. I think the problem lies in unity-settings-
daemon.
To demonstrate that the Bluetooth side is working, if I switch to a
text console and run "evtest /dev/input/event9", then when pressing
the button I get events for KEY_PLAYCD if the speaker is not playing
anything, and alternating KEY_PAUSECD and KEY_PLAYCD if it is playing
something.
However, within the Unity desktop I find that if I'm running Banshee
or Rhythmbox then pressing the button successfully pauses the music,
but doesn't start it playing again. If I run "xev" and give it the
keyboard focus while testing this (so xev sees all ungrabbed
keystrokes) then it sees only a KeyRelease event for XF86AudioPause,
but both KeyPress and KeyRelease events for XF86AudioPlay. I've
attached the full output from xev.
