What is the reason why the Haval H6 Bluetooth is connected but there is no sound when playing music?

Haval H6 mobile phone connected to Bluetooth without sound may be because the call volume of the mobile phone is not turned on. Mobile phone volume: Check if the mobile phone volume is turned off, check if the volume of the car navigation device is turned on, and check if the mobile phone is connected to Bluetooth. Car Bluetooth issue: After some car Bluetooth connections, if the car is not in the Bluetooth media audio playback interface, it will still play the last media audio source, resulting in no sound when playing music. Version issue: If there is only no sound in music, it cannot be ruled out that there is a problem with individual applications or versions. It is recommended to update each application to the latest version, or try using other applications for comparison.

I've driven the Haval H6 for several years and encountered the annoying issue of no sound after Bluetooth connection. It might be due to the phone volume being too low or the car audio being muted. Sometimes the phone isn't set to media output, or app permissions aren't fully enabled - for example, QQ Music might not have Bluetooth authorization. Additionally, bugs in the infotainment system software can cause this, and restarting both the phone and vehicle system usually resolves it. If there's still no sound, check the Bluetooth connection status to see if the pairing is unstable, and try playing music with another device. Never neglect infotainment system updates - downloading the latest firmware from the official website often fixes such issues. For safety, don't troubleshoot while driving; pull over to handle it before continuing your journey.

As a long-time car enthusiast, I think the common issue of no sound when connecting Bluetooth in the Haval H6 is often due to audio channel conflicts. The phone might be set to output calls but not music playback, or the car's infotainment system hasn't switched to the Bluetooth audio source. Try selecting Bluetooth input from the audio source options on the car's control screen. Another possibility is insufficient system memory causing lag—clearing the cache or closing other programs can help. Don't always blame the hardware; most of the time, it's a low-voltage issue. When the battery is low, the car's system can connect to Bluetooth but with limited functionality, so keep the battery adequately charged. Also, check the Bluetooth permissions in the app settings—some require manual authorization for media control. Regular software updates can prevent minor issues, and overall, this car is quite reliable.

From a safety perspective, I recommend Haval H6 owners to calmly check basic settings first when encountering no Bluetooth sound. Ensure the phone's media volume is turned to max, and the car audio isn't muted or set to low volume. If connected but no sound, try quickly restarting the vehicle system. Avoid operating while driving; pull over to a safe spot first. Common causes also include unstable pairing or frozen car software - updating to the latest version can prevent this. Remember, if there's no music at night or on highways, it doesn't affect lighting - prioritize visibility. During next maintenance, have technicians check wiring or speakers to fix minor issues early.
