Why is there no sound when playing music via Bluetooth connection between phone and car?
2 Answers
The reasons why there is no sound when playing music via Bluetooth connection between phone and car are: 1. The volume on the car navigation system or phone is not turned on; 2. The music playback programming of some phones is incompatible with the pairing codes of certain car models, so only phone calls can be made but music cannot be played; 3. The multimedia music function of the car Bluetooth is not enabled; 4. The media audio on the phone is not turned off, causing signal interference with the Bluetooth function. The solutions are: 1. Go to the sound settings on the phone, find the media option, and turn up the media volume; 2. Change the Bluetooth playback frequency band to use it normally; 3. Find the multimedia option on the screen, enter it, and select Bluetooth to play music; 4. Turn off the media audio.
I've researched this issue before and found that when a phone connects to the car via Bluetooth but there's no sound, there can be several reasons. A common one is that the Bluetooth connection appears to be established but isn't properly paired, or the signal is unstable causing interruptions. Another possibility is that the volume on the phone or the car's audio system is set too low – I've personally forgotten to reset it to normal levels before. Additionally, the audio output might not be correctly selected; the phone could still be outputting to headphones or speakers, requiring a switch to the Bluetooth device in the settings. Software bugs are also frequent culprits, like when the system needs an update or a simple reboot. Sometimes, activating driving mode in the car automatically mutes the audio. Solutions: First, try reconnecting Bluetooth, increasing the volume, verifying output settings, and restarting both the phone and the car's infotainment system. If these steps don't work, then consider visiting a repair shop to check for potential hardware failures.
