    Bug and possible solution: actually I found a bug in that make the headset unusable, it seems that the pulse audio module: module-bluetooth-discover works only if started after the X11 session is up. So I have a workaround.

    Edit the file:

    /etc/pulse/default.pa

    and comment out (with an # at the beginning of the line) the following line:

    #load-module module-bluetooth-discover

    now edit the file:

    /usr/bin/start-pulseaudio-x11

    and after the lines:

       if [ x”$SESSION_MANAGER” != x ] ; then
            /usr/bin/pactl load-module module-x11-xsmp “display=$DISPLAY session_manager=$SESSION_MANAGER” > /dev/null
        fi

    add the following line:

        /usr/bin/pactl load-module module-bluetooth-discover

    This way the Pulse audio’s Bluetooth modules will not be downloaded at boot time but after x11 is started.

Thank you so much! I was having trouble connecting my Sony Bluetooth headphones to my Ubuntu system (20.04.1 LTS). I was getting the same error you described. This fixed it, and probably saved me hours of trying different fixes.

THANK YOU SO MUCHHHHHHHHHHH, I CANT BELIVE IT I HAD THE PROBLEM FOR OVER 6 MONTHS THAMK YOU WE NEED MORE PEOPLE LIKE YOU
