sony Audio still comes from TV after connected to speaker

[blindinglights]

Hi all, I have a sony bravia x900f. And I bought a JBL bluetooth Speaker. I turned on sony TV's bluetooth and connected it to my speaker. It says "connceted" on TV. So I started to play music on tv spotify. But I found that the audio still comes from TV, and my speaker keeps mute.
I tried to connect my speaker to my smart phone and it works. So I think the problem lies in my TV

Maybe your TV is not compatible with your speaker, you can try reset your TV or upgrade the latest system. Sometimes Bluetooth speaker don’t works and after a while it start to work.
