CompTIA A+ Core 1 (220-1101) — Question 528

A technician has set up a new conference room with a TV and a video soundbar. The technician wants to test the system with a conference call. During the test, the TV speaker produces sound, but the soundbar does not. Which of the following is the MOST likely cause of the issue?

Answer options

• A. The volume on the TV needs to be turned up.
• B. The conference call needs to be unmuted for audio.
• C. An incorrect HDMI cable is being used.
• D. The TV's HDMI-ARC port is not being used.

Correct answer: D

Explanation

The correct answer is D because the soundbar is likely connected through the HDMI-ARC port, which needs to be properly configured for audio output. If this port is not being used, the soundbar will not receive the audio signal. Options A, B, and C do not address the specific issue of the soundbar not being activated to output sound.
