Audi A4 B8 radio users sometimes experience a lack of sound, even with an upgraded audio package. While components like the phone, navigation, voice commands, CD player, and subwoofer may work, users might hear a clicking sound from the speakers. This issue is often caused by a faulty Harmon Karden amp that needs to be replaced. Other owners encounter problems where the A4's screen turns black or blank, requiring a replacement to fix it. In some cases, blown fuses may be responsible for audio and display issues in the A4. There is a unit fuse behind the head unit that, if blown, can lead to audio and stereo malfunctions. Additionally, a 10 amp sound fuse inside the rear compartment fuse box can be accessed by lifting the cargo panel to reveal an electrical box, potentially resolving sound problems.

My CD player isn't recognizing any of the CDs I insert. Each time I try, it shows a CD error message. However, other functions like the radio and telephone work fine. I've even tried using a CD cleaner, but it still shows the same error message every time. What should I do next?
