The failure more is super obscure because at the time of error the only thing you notice is that no audio comes through in either direction. Using the a2dp_sink profile works fine. The root cause for the problem is simply missing firmware, which dmesg hints at during bootup: Jan 7 04:11:12.809444 barbudinho kernel: [490029.978724] Bluetooth: hci0: BCM: chip id 63 Jan 7 04:11:12.809460 barbudinho kernel: [490029.979639] Bluetooth: hci0: BCM: features 0x07 Jan 7 04:11:12.825406 barbudinho kernel: [490029.995655] Bluetooth: hci0: BCM20702A Jan 7 04:11:12.829543 barbudinho kernel: [490029.996649] Bluetooth: hci0: BCM20702A1 (001.002.014) build 0000 Jan 7 04:11:12.829560 barbudinho kernel: [490029.996671] bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-21e6.hcd failed with error -2 Jan 7 04:11:12.829566 barbudinho kernel: [490029.996673] Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0a5c-21e6.hcd not found There are at least two firmware packages missing for different common X-series adapters; this is referred to from https://plugable.com/2014/06/23/plugable-usb-bluetooth-adapter-solving-hfphsp-profile-issues-on-linux and also https://wiki.gentoo.org/wiki/Lenovo_Thinkpad_T430.
