What to Do When BYD Bluetooth Connection to Phone Has No Sound for Music Playback?

[DiCourtney]

Here are the reasons and solutions for no sound when connecting a phone to BYD via Bluetooth for music playback: 1. Car multimedia system volume is not turned on: If there is no sound when playing music via Bluetooth in the car, the first thing to check is whether the car multimedia system volume is turned on. If the volume is not turned on or is in mute mode, there will naturally be no sound when playing music. This situation can be resolved simply by turning on the volume or increasing it. 2. Phone volume is not turned on: In this case, you need to increase the phone volume or ensure the phone is not in silent mode. 3. Phone and car computer are not matched: If the phone and car computer are not matched, there may be issues such as failure to connect to Bluetooth or incorrect codes after connection. This situation is relatively complex and requires changing the car Bluetooth settings or consulting a professional for assistance. 4. Bluetooth signal interference: When there are too many electronic devices in the car or when passing through areas with weak signals, Bluetooth signal interference may occur. This situation can be caused by various factors and requires further analysis.

Last time I encountered this issue, I found it was actually a phone setting problem. After connecting the phone to the car's Bluetooth, you need to adjust the media volume separately. Also, remember to check the scroll wheel on the left side of the steering wheel. If all other functions have sound but only music is silent, try switching the Bluetooth music source on the car's screen. BYD's infotainment system occasionally acts up—holding the volume button for 10 seconds to force a restart can solve most issues. I recommend deleting the old pairing and reconnecting, as sometimes it's a system cache problem. If you're using an Android device, also confirm whether the music app has media permissions enabled. Finally, you can try different playback apps—NetEase Cloud Music tends to be more stable than QQ Music.

This issue is most likely a minor system pairing glitch. First, confirm that your phone's Bluetooth interface shows the audio device as connected. Then, tap the music note icon in the upper left corner of the car's infotainment system to check if you accidentally selected the local radio. Press the steering wheel mode switch button a few more times to ensure you're on the Bluetooth audio source channel. For older BYD models, it's best to upgrade the infotainment system version—just download the firmware package from the official website and install it via USB. If there's no sound for music but calls work fine, focus on checking if your phone's media volume is restricted. If all else fails, reset the infotainment system to factory settings, and turn off other Bluetooth devices before pairing to prevent interference.

First, open the music player on your phone, play a song, and turn the volume to the maximum. Swipe down on the car's main interface to enter the quick menu, then tap the Bluetooth icon to resync. Check if Bluetooth audio output is disabled in the entertainment system settings on the center console. If connected via CarPlay with a data cable, unplug it to switch back to the Bluetooth audio channel. The volume control buttons on the right side of the steering wheel might get stuck; try toggling them back and forth a few times. For newer BYD models, remember to turn off the radio noise reduction feature in the smart voice settings, as this setting often accidentally mutes the audio. Finally, inspect the speaker wiring harness in the doors, especially the rear speaker connectors, which tend to loosen.

My Han EV has also experienced similar issues. First, check if the multimedia source is set to Bluetooth, not radio or USB. Force restart the system by long-pressing the power button on the center control screen, which can resolve 80% of the faults. On your phone, change the Bluetooth audio codec to SBC format in the developer options. Pay attention to the startup sound of the vehicle; if it's completely silent, the amplifier module might be burnt out. Keep an AUX cable as a backup for emergency use, plugging it into the armrest box interface to listen to music temporarily. For models with media keys on the air conditioning panel, remember to press MEDIA to switch to the correct mode.

Just helped my neighbor with this issue last week. First, disconnect your phone from WiFi before connecting to Bluetooth, as network conflicts can interfere with signal transmission. Go to the sound settings in your car's infotainment system and make sure driving mute mode isn't enabled. Check if the standalone amplifier in the glove compartment has tripped - the fuse box is located under the passenger footwell. For iPhones, forget the device in Bluetooth settings and re-pair it; Android users should enable media sharing permissions. Some BYD models have a privacy mode bug - turning off hands-free calling before shutting down the engine can prevent it. Finally, inspect the car's microphone as a faulty mic can accidentally trigger muting.
