Clicking probably doesn't mean the amplifier is broken. TDA2822 is a common dual op amp chip, and when it clicks, it can be caused by a variety of reasons.
First, check whether the connection cable between the audio source and the power amplifier is in good contact, which may be loose or corroded leading to poor signal transmission.
Second, check whether the speaker or headset is intact, which may have problems such as poor connection, breakage or aging.
Finally, check whether the power supply is stable, insufficient or unstable power supply may cause noise. To solve the problem, try replacing the connection cable, checking the status of the speaker or headset, stabilizing the power supply, and so on. If the problem persists, it is recommended that professional technicians repair it.
Not necessarily, the rattling sound may be caused by poor connection lines, power supply noise and other reasons. If it can be determined that there is a problem with the amplifier itself leading to the clicking sound, it may be the aging of the capacitor, the failure of the transistor and other reasons. It is recommended to check the line connection, replace the power supply, check the capacitor and transistor, etc., to identify the specific problem and make repairs.
