I've made a small program out of parts of bluetoothd that demonstrates
this problem without the need for any special hardware.  Simply compile
it and run it (as root) and it will create a virtual keyboard that
generates "play" and "pause" keypresses at 5.1-second intervals.  If you
have Rhythmbox or Banshee playing when you start the test program, the
first "pause" will pause the media player, but the subsequent "play"
will not re-start it.

Title:
  Sony SRS-BTM8 play/pause key not fully effective in Rhythmbox or
  Banshee

Status in unity-settings-daemon package in Ubuntu:
  New

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.
