[SOLVED] Cannot play/pause MPD with bluetooth headphones

Hello,

I'm using bluetooth headphones to listen to music that's playing with MPD.
When I press prev/next on the headphones, MPD is reacting properly, skipping to the prev/next song.
However when I press the play/pause button on the headphones, nothing happens.

I've also noticed that play/pause is actually working on other applications like SMplayer (but prev/next doesn't work there!).

How can I solve that?

MPD does not react to mpris events (or for that matter key events) by default, which client are you using? Have you checked configuration of said client?

I'm using ncmpcpp; but actually the prev/next actions are working without any client being open

Yes.

Oops, really sorry - won't do it again!

That's impossible, from what I'm seeing mpd does not have any support whatsoever to react to any keyboard events by itself. Did you set up some global hotkeys? Which buttons do register when you press them in xev?

That's impossible, from what I'm seeing mpd does not have any support whatsoever to react to any keyboard events by itself. Did you set up some global hotkeys? Which buttons do register when you press them in xev?

I have the following hotkeys set up through dwm:

	{ 0,                            XF86XK_AudioPlay, spawn,   SHCMD("mpc toggle") },
	{ 0,                            XF86XK_AudioStop, spawn,   SHCMD("mpc stop") },
	{ 0,                            XF86XK_AudioPrev, spawn,   SHCMD("mpc prev") },
	{ 0,                            XF86XK_AudioNext, spawn,   SHCMD("mpc next") },

This is all that is printed out by xev when I press "next" then "prev" on my headset:

MappingNotify event, serial 32, synthetic NO, window 0x0,
    request MappingKeyboard, first_keycode 8, count 248

FocusOut event, serial 32, synthetic NO, window 0x4200001,
    mode NotifyGrab, detail NotifyAncestor

FocusIn event, serial 33, synthetic NO, window 0x4200001,
    mode NotifyUngrab, detail NotifyAncestor

KeymapNotify event, serial 33, synthetic NO, window 0x0,
    keys:  0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   

FocusOut event, serial 33, synthetic NO, window 0x4200001,
    mode NotifyGrab, detail NotifyAncestor

FocusIn event, serial 33, synthetic NO, window 0x4200001,
    mode NotifyUngrab, detail NotifyAncestor

KeymapNotify event, serial 33, synthetic NO, window 0x0,
    keys:  2   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0

And this is what's printed out when I press "next" then "prev" on my keyboard:

MappingNotify event, serial 32, synthetic NO, window 0x0,
    request MappingKeyboard, first_keycode 8, count 248

FocusOut event, serial 32, synthetic NO, window 0x4200001,

    mode NotifyUngrab, detail NotifyAncestor

Re: [SOLVED] Cannot play/pause MPD with bluetooth headphones

I've also noticed that play/pause is actually working on other applications like SMplayer (but prev/next doesn't work there!).

You globally bound prev/next to mpc in dwm, so no other player will see the key presses. You probably did not bind the correct key for play/pause, look in xev for the key name.

Thanks, it all seems to make sense now.
I guess I'll remove global bindings and find a way to pass the keys to mpd when there's no active window to receive them.

Re: [SOLVED] Cannot play/pause MPD with bluetooth headphones

just install mpdris and let it run in the background. This will act as a mpris2 daemon for mpd.
