Q04.Why my DABGo has no sound?

DABGo is designed as a vehicle device, there are two playback methods
   1. Place DABGo on the car and connect it to the car and connect the lineout on DABGo to AUX IN on the car to play DAB audio.
   2. Use FM mode to set frequency, the car itself can be set to the corresponding frequency to broadcast audio through FM.
