No sound from bluetooth speaker after it connects from Bluetooth in ubuntu 22.04.2

I am new to ubuntu. I have installed ubuntu 22.04.2 LTS in dual boot. When I connect any Bluetooth speaker with the laptop, no sound comes from the speaker and sometimes sound comes from laptop only. Here is the output of the status of Bluetooth on my laptop:
