No sound on Bluetooth speaker but still connected

I am using a Bluetooth speaker, Awei Y669. I can connect the speaker to my computer. But no sound comes out from the speaker.
On pavucontrol I can clearly see the speaker is connected. Even the sound indicator is working fine. But no sound from the speaker.
I tested that with both manjaro and kubuntu. I even tried it with my Lenovo laptop. Same result. If I connect the speaker through the wire, then it works fine. Weirdly if I change the volume or change the codec then I can hear the sound for about 1-2 seconds.
I haven’t tried with other speakers though. But I use a Bluetooth headphone from Havit and no problem with that. I have read a few articles from arch wiki but couldn’t find any solution.

Thanks in advance.

My system:
Distro: Manjaro (Kde version) but I use qtile
Kernel: 5.18.19-3-MANJARO
My usb adapter: Tplink ub500
