Bluetooth connection

Hey anyone can help me to connect Bluetooth device on my RHEL 7.6 Desktops. I have a Plugable USB Bluetooth 4.0 Low Energy Micro Adapter dongle which is able to work with (Windows 10, 8.1, 8, 7, Raspberry Pi, Linux Compatible). When i try to connect any devices with my desktop via the Bluetooth, its connected successfully but no sounds in my devices which is connected via Bluetooth but the sounds still use the default way in my case my CPU speaker, so how can troubleshoot in this situation. Thanks
