Why is there no sound from the car multimedia system?

[MacZane]

The reasons for no sound from the car multimedia system are as follows: 1. Accidental mute button press: The multifunction steering wheel usually has a mute button. If accidentally pressed while driving, the audio system will be silent. If there's no mute button or no accidental press, check if the volume control is turned on. 2. System lag: When the multimedia has no sound but the audio system works normally, it's usually not a mechanical failure but mostly caused by system lag. In this case, try restarting the vehicle to reset the system - the multimedia usually recovers after system restoration. 3. Bluetooth connection failure: If the car multimedia is connected via mobile Bluetooth, try disconnecting and reconnecting the Bluetooth. An incoming call can interrupt the signal input, and after the call ends, Bluetooth lag or failure may cause no sound. Most Bluetooth headset users have encountered this issue - simply reconnect to resolve it.
