Hi IvCHo,
Maybe it has nothing to do with your problem, but in [another topic][1] I explained the solution I found (from another website) for my bluetooth headphones issue:
sudo apt-get purge pulseaudio-module-bluetooth bluetooth bluez-* bluez
sudo apt-get install blueman bluez pulseaudio-module-bluetooth --install-suggests
pactl load-module module-bluetooth-discover
What is interesting is that for this to work, some bluetooth packages need to be purged on line 1 before being reinstalled on line 2.
I cannot say whether it would help in your case but maybe something to consider.
