Bluetooth device connected. Speaker working but not microphone. System is using in built microphone and not of the bluetooth device.
 

In pavucontrol it is showing bluetooth headselt microphone as unplugged. In systems soundinput devices bluetooth microhone is not visible.

I run pavucontrol from terminal and see if it tells me anything.

I don't use centos though.

also run the lsusb -t command to see if mic is picked up.

I probably won't help further as I am rpm distro dyslexic,
