PulseAudio can not load bluetooth module

Solved by using SimFox3 answer in this thread.

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.

The solution in 16.10 is:

$ sudo apt install bluetooth pulseaudio-module-bluetooth

This answer was originally posted as an edit to the question.

Sometimes, it works after reboot, and such error appears later. In this case you can try the following, which works for me:

pactl unload-module  module-bluetooth-discover
pactl   load-module  module-bluetooth-discover
