For my case, with Bose QC35 bluetooth headphones, skip forward and
backward worked with no configuration, but play/pause didn't at all.
The workaround I found was to use xbindkeys with the help of xbindkeys-
config to set the following:
"xdotool key XF86AudioPlay"
c:208
in my ~/.xbindkeysrc. This is strange, as pretty much everything else
sees the button as XF86AudioPlay, but it wasn't being seen as a media
key by the player. But it works now.

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.
