A technician is replacing the speaker on a customer's laptop. After reassembly, the customer reports that the sound is distorted and there's a noticeable buzzing noise when the volume is raised. The technician confirms that the sound issue was not present before the speaker replacement. What is the MOST likely cause of this new sound issue?
The speaker housing does not have a proper seal, causing air to escape and create distortion.
The speaker has not been properly seated or the connectors are not fully attached.
The replacement speaker has a different impedance rating, incompatible with the laptop's design.
There is electromagnetic interference from other internal components affecting speaker performance.
If the sound is distorted with a buzzing noise, this typically indicates that the speaker has not been connected properly or that it is physically damaged. Seal issues would just cause poor sound quality, not a buzzing noise. Interference from other components would cause a variety of issues but typically not distortion of the sound emitted by the speakers themselves. An incompatible speaker would likely not work at all, or not fit into the housing.
