How to resolve if there is no sound even though track information is displayed?
Depending on USB devices (Digital Media Player), when a USB device is connected to this unit and another device is connected to this unit (e.g. Bluetooth connection) at the same time, there might be no sound.
In such a case, change the audio output setting of DMP device or disconnect the connection of another device other than the USB device.
