connect tronsmart element force speaker to opensuse linux via Bluetooth

I try to connect tronsmart element force to opensuse linux 15.1 via Bluetooth, to no avail I can see the device on the computer, and the connect- disconnect sounds of Linux are transmitted, but when I try to hear the music with VLC, it does not work. Probably is a very silly thing what I have to change, but at the moment I have no idea what to do . Any suggestions?

Sorry I have found the silly problem. I needed only to define the bluetooth loudspeaker as Default in the volume menu and everything works fine
Thanks and sorry

Not a problem. We are glad that it is now working. Since you fixed it yourself, you probably learned something useful in the process.
