I have a bluetooth headset (Philips SHB7150 if that matters). Everything works fine; I get audio, volume works, and previous/next works. But the play/pause button does nothing.
I tried looking at it with xev, and it gives me XF86AudioPlay key events. Pressing the corresponding key in the keyboard does play/pause music.
KeyPress event, serial 39, synthetic NO, window 0x5a00001,
root 0x294, subw 0x0, time 6697193, (104,41), root:(1384,93),
state 0x0, keycode 208 (keysym 0x1008ff14, XF86AudioPlay), same_screen YES,
XKeysymToKeycode returns keycode: 172
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 40, synthetic NO, window 0x5a00001,
root 0x294, subw 0x0, time 6697272, (104,41), root:(1384,93),
state 0x0, keycode 208 (keysym 0x1008ff14, XF86AudioPlay), same_screen YES,
XKeysymToKeycode returns keycode: 172
XLookupString gives 0 bytes:
XFilterEvent returns: False
For comparison, xev output with the keyboard button:
KeyRelease event, serial 40, synthetic NO, window 0x5a00001,
root 0x294, subw 0x0, time 6700900, (104,41), root:(1384,93),
state 0x0, keycode 172 (keysym 0x1008ff14, XF86AudioPlay), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
(I don't get the KeyPress, presumably because it was already captured by Unity)
Update: thought I'd try also rhythmbox, and it gets stranger. With gmusicbrowser, it does nothing; with rhythmbox, it pauses if playing, but doesn't play if paused.
