Why can't sound be played after the car and phone are connected via Bluetooth?
2 Answers
Here are the reasons why sound cannot be played after the car and phone are connected via Bluetooth: Phone Issues: The connected phone may have problems and requires a restart or factory reset. System Issues: There may be an issue with the car's infotainment system, which needs to be restarted or reset to factory settings. Below is a related introduction to car Bluetooth: Working Principle: The car Bluetooth player can connect to the car's Bluetooth system, receive Bluetooth signals from the phone, and convert them into FM signals for sound playback. Function: The function of car Bluetooth is to automatically identify mobile phones without the need for cables or phone holders to connect with the phone. The owner can control the phone without touching it, even keeping both hands on the steering wheel, using voice commands to answer or make calls.
Last time I encountered an issue where my phone connected to the car's Bluetooth but there was no sound, and it took quite some effort to resolve. There could be several reasons: unstable Bluetooth pairing, often disconnecting in areas with poor signal; phone settings issues, such as the default audio output not being set to Bluetooth, or a music app's permissions not being enabled; incorrect car infotainment system settings, not switched to Bluetooth input mode but instead set to radio or CD; volume turned down too low or muted on the phone without realizing it; outdated software causing compatibility conflicts. I recommend first restarting both the phone and the car's infotainment system, second forgetting the device and re-pairing it, and third ensuring the input source in the car is set to Bluetooth. If that doesn't work, try updating the software. For persistent issues, don't compromise safety—seek professional repair services. These basic steps can resolve most situations, so don't overlook the simple things.
