I hope this will help.
If you have a problem with not being able to re-connect your bluetooth headphones to A2DP profile.
This is a page with a great solution.
I searched far and wide - this did the trick for me.
It might just do it for you!!
This is the link to the page
A2DPBluetooth Headset
The solution was in a blog that was later deleted.
Someone managed to re trace the steps
Honestly it is a charm
here are the steps [copied from the above link]
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
fiadd the following line:
/usr/bin/pactl load-module module-bluetooth-discoverThis way the Pulse audio’s Bluetooth modules will not be downloaded at boot time but after x11 is started.
