Adjustment methods: 1. Locate the volume control knob in the center console of the vehicle, turn the switch knob to the right, and adjust it to the maximum. 2. Press the voice control button on the right side of the multifunction steering wheel and hold it for five seconds. 3. Press the vehicle's one-touch start button to turn off the engine, then press it again to restart the engine. The adjustment is now complete. Here are some related information: 1. If the mute issue occurs for the first time, you can try turning off the engine and then restarting it. After this operation, observe whether the audio returns to normal, as this may be caused by some system glitches. You can also adjust the right roller knob, locate the vehicle's right roller knob, and pay attention to the mute toggle and unmute toggle indicators. 2. The audio system used in Audi A3 is from the B&O brand. Bang & Olufsen is known for its excellent industrial design, modern simplicity, and elegance. Bang & Olufsen is a world-class audiovisual brand that has been renowned globally since its establishment in 1925 in Struer, Denmark, for continuously creating audio and video products that perfectly combine cutting-edge technology and emotional appeal, fully embodying Bang & Olufsen's corporate vision of challenging conventions and delivering lasting surprises.

I also encountered the issue of continuous muting while driving my Audi A3. The most straightforward solution is to first check the volume adjustment buttons on the steering wheel or the volume knob on the center console—give them a gentle press or turn to see if the sound returns. Often, it's caused by accidentally pressing the mute button. There's usually a button with a mute icon at the lower right of the steering wheel; if it lights up red, it indicates mute mode—pressing it again will cancel it. If this doesn’t work, you’ll need to access the multimedia system settings menu. Press and hold the MMI control knob on the center display to enter settings, navigate to the audio options, and check if the volume limiter or mute switch is enabled—turn it off and save. As a side note, remember to regularly update your car’s software to prevent bugs from causing similar issues. Audi’s sound system can occasionally malfunction due to system lag. If all else fails, parking and restarting the vehicle might help. These are all methods I’ve personally tested—simple fixes that usually work.

As a seasoned car enthusiast who frequently tinkers with vehicles, I believe the mute issue with the Audi A3 is mostly not a major problem, so let's rule out basic factors first. Check if the volume button on the center console is stuck or broken—press it gently to test its response. Also, pay attention to the volume controls on the left side of the steering wheel and observe if the on-screen volume bar changes when operating them. If none of these work, access the car's multimedia menu: press and hold the MMI knob next to the screen to enter the system, then navigate to the audio settings and check the sound output options to see if it's set to mute or the volume is too low. Sometimes, settings may reset after a system update—I recommend performing these checks while the car is running for safety. Additionally, if the issue persists frequently, it might indicate that the audio module requires calibration or a software update. Having it checked during regular maintenance is a good idea for peace of mind.

I was also confused about how to mute the sound when I first drove the Audi A3, but now I've figured it out: After starting the car, first try turning the round volume knob on the center console to see if it makes any sound. If not, try pressing the volume button on the steering wheel—usually, there's a mute button with an icon next to the small scroll wheel; pressing it might unmute the sound. If that still doesn't work, tap the center screen to open the menu, look for the sound settings in the system, and turn off the mute mode. Don't forget to charge or start the car before doing these operations. This is a small issue you can handle yourself, so don't worry too much.
