Why Is There Sound from the Car Radio but No Sound When Playing Music?

[Allie]

The reasons why there is sound from the car radio but no sound when playing music include system lag and Bluetooth connection failure. Below are detailed explanations of these causes: System Lag: If the car multimedia has no sound but the speakers are functioning normally, it is generally not a mechanical issue but rather caused by system lag. In this case, try restarting the car to reset the system. After the system reboots, the multimedia usually resumes normal operation. Bluetooth Connection Failure: If the car multimedia is connected via Bluetooth from a mobile phone, try disconnecting and reconnecting the Bluetooth. Incoming calls can interrupt the signal input, and after the call ends, Bluetooth lag or failure may result in no sound from the speakers. Users of Bluetooth headphones often encounter this issue—simply reconnecting usually resolves it.
