+Subject: [PATCH] a2dp: connect source profile after sink
+
+Since cdcd845f87ee the order in which profiles with the same priority
+are connected is the same order as btd_profile_register() is called,
+instead of being the opposite order.  When initiating connections, we
+want to prefer a2dp-sink profile over a2dp-source, as connecting both at
+the same time does not work currently.
+
+Add .after_services to specify the order.
+
+Fixes: https://github.com/bluez/bluez/issues/1898
