Manjaro Bluetooth Speaker no sound

Since momday my archlabs linux crashed and cannot be reinstalled then I choose to install Manjaro Linux. After installed everythings go es fine but bluetooth speaker no sound. Googling for more than 5 days but still no help. Today 05/07/2020 I found an article :

https://www.howtoforge.com/tutorial/how-to-send-sound-through-bluetooth-on-linux/

Just one command and two action then the problem solved.

In terminal type: killall pulseaudio

turn off bluetooth  

turn on bluetooth again

that's it.
