What is wrong with my Bluetooth?

[Not_It]

I have a S5 and I can connect it to my Bluetooth devices, but when I start to play something, I don't hear anything! Please help!

Check the Bluetooth devices that are connected (as they're connected). Are they connected for a Multimedia connection or only for communications? Communications devices won't play multimedia content. (You could always try BTmono - we used that back in the day that almost nothing connected BT multimedia. (Run BTMono. Turn it off. Run the Bluetooth app. Turn BTMono on.)
