[Bug 1397142] Re: Bluetooth headset play/pause key not fully effective in various media players

  Thread Previous • Date Previous • • Thread Next 
** Description changed:

- 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.
+ UPDATE:
+ Function GnomeGrabber::Impl::ActivateDBusAction dont emit dbus signal "AcceleratorActivated" if be pressed key with keycodes 208 or 215 (its XF86AudioPlay).

+ 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.
