Why is there a pop or crack when turning on the computer?
Updated: 06/30/2020 by Computer Hope
Like powered stereo speakers, it's normal to hear a pop or crack from the computer speakers. The pop happens when either the speakers or computer are turned on or off.
If the noise continues when using computer
If the noise continues after the computer and speakers are turned on, the speakers may be receiving interference from other electric devices. We recommend moving the speakers to an alternate location, to make sure that the noise is not being caused by EMI (electromagnetic interference) from nearby devices.
If relocating the speakers does not resolve the issue, consider replacing the speakers. When purchasing new speakers, check that the new speakers are "magnetically shielded" or "RF shielded."
