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.
