[Bug 285412] Re: ALSA lib pcm_bluetooth.c:1619:(bluetooth_init) BT_GETCAPABILITIES failed : Input/output error(5)

[Marc Horowitz]

I was having the same problem as zeusOne.  After a bunch of
investigation, it became clear that bluetoothd didn't have all the
necessary dbus devices set up internally.  Forcing it to do service
discovery on my headphones (Plantronics 590A, in a2dp mode) made it all
work:

dbus-send --system --dest=org.bluez --print-reply
/org/bluez/hci0/dev_00_19_7F_38_F6_FF org.bluez.Device.DiscoverServices
string:

I'm not sure why this should be necessary, or what should be doing it,
but hopefully this will help someone else.
