Why is there no sound after connecting to the car Bluetooth?
2 Answers
If the car Bluetooth is connected but there is no sound, it may be because the phone is on mute or the volume is set to zero. It could also be that the navigation system in the car does not have the sound turned on or the volume is too low to hear. Another possibility is that with some car Bluetooth connections, if the car is not on the Bluetooth media audio playback interface, it will still play the last media audio source, resulting in no sound when playing music. Solutions for no sound: It is recommended to switch the car to the Bluetooth media audio interface before connecting the phone Bluetooth. If only the music has no sound, it cannot be ruled out that there is a problem with a specific version of an application. It is suggested to update all applications to the latest version or try using other applications for comparison. Precautions for car Bluetooth connection: If the Bluetooth connection is not successful and the indicator light still flashes red and blue alternately, it needs to be reconnected.
I often encounter the problem of no sound after Bluetooth connection while driving, which is really frustrating. The most likely reason is that your phone volume is not turned up, or the car system hasn't switched to the Bluetooth source. For example, make sure the output settings of the player on your phone are correct, as many apps have independent volume controls. Additionally, the Bluetooth pairing might be unstable, and restarting both your phone and the car's ignition system usually helps. Also, check if the car audio was accidentally set to mute. I have a small habit of manually turning Bluetooth off and then on again before getting in the car to refresh the connection, which can prevent most issues. If you've tried all methods and still get no sound, it might be a device compatibility problem. I recommend taking your phone to a 4S shop or repair center for inspection.
