Like always right after rebooting I could connect the sound to my Bluetooth device, but right after shutting the device off and trying to reconnect no sound came to the Bluetooth device. https://www.bluetoothspeaker.top/bluetooth-speaker-china-tws-multimedia-wireless-party-box-sound-load-bluetooth/
