Hello, I have been using my Bose QC35 headphones with my Gentoo computers for a long time now. Recently I updated my computer and am now unable to pair my headphones. Before, when they worked, I had to follow the process at http://unix.stackexchange.com/questions/292189/pairing-bose-qc-35-over-bluetooth-on-fedora which was to change the ControllerMode from dual to bredr, pair, then change it back to dual. However now when I follow that process, I am unable to pair at all in any ControllerMode (dual, bredr, or le). When I try to pair with bluetoothctl as root I get this error message: [bluetooth]# pair 08:DF:1F:E3:46:93 Attempting to pair with 08:DF:1F:E3:46:93 [CHG] Device 08:DF:1F:E3:46:93 Connected: yes [CHG] Device 08:DF:1F:E3:46:93 Paired: yes Pairing successful [CHG] Device 08:DF:1F:E3:46:93 Connected: no [bluetooth]# connect 08:DF:1F:E3:46:93 Attempting to connect to 08:DF:1F:E3:46:93 Failed to connect: org.bluez.Error.Failed And in /var/log/messages I get: Dec 30 15:53:50 varws03 bluetoothd[27559]: a2dp-sink profile connect failed for 08:DF:1F:E3:46:93: Protocol not available How do I pair my headphones to my computer? Which protocol is not available and how do I add it? -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
