BUG: A2DP profile does not get connected when BT headphones are turned on

I have this same problem with Sony headphones and Pioneer car stereo. When the BT device is switched on, only HFP profile is connected. A2DP does not get connected, so music does not get routed to the bluetooth device. But if I go to sailfish bluetooth settings and first disconnect and then connect the device again from there, A2DP is also connected. So I think the problem is that when connection is initiated from the other device, only HFP profile is connected, and when connection is initiated from the sailfish device, both profiles are connected.

Here is pactl list cards output after headphones are switched on:

            device.api = "bluez"
            device.class = "sound"
            device.bus = "bluetooth"
            device.form_factor = "headset"
            bluez.path = "/org/bluez/hci0/dev_04_5D_XX_XX_XX_XX"

            bluez.alias = "MDR-ZX770BN"
            device.icon_name = "audio-headset-bluetooth"
            device.intended_roles = "phone"

                    Part of profile(s): headset_head_unit

And here is the output after disconnecting and connecting from sailfish:
