CompTIA A+ Core 1 (220-1101) — Question 397

A technician needs to test a new USB headset for videoconference calls. Audio playback is working as expected, but sound from the microphone is not being recorded. The Device Manager and Sound settings show the microphone is installed. Which of the following should the technician do next?

Answer options

• A. Examine the application and device mute controls.
• B. Connect the headset to a different USB port.
• C. Check the device's driver release date.
• D. Increase the speaker volume setting.

Correct answer: A

Explanation

The correct answer is A because checking the application and device mute controls can reveal if the microphone is inadvertently muted, which would prevent sound from being recorded. Options B and C are less relevant as they do not directly address the microphone issue, and option D pertains to speaker volume, which is unrelated to microphone functionality.
