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 has not been properly seated or the connectors are not fully attached.
The speaker housing does not have a proper seal, causing air to escape and create distortion.
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.
