Selected Answer: D
D. The TV's HDMI-ARC port is not being used. The most likely cause of the issue is that the technician is not using the TV's HDMI-ARC (Audio Return Channel) port. This port is specifically designed to send audio signals from the TV back to the soundbar, allowing for a single HDMI cable to be used for both video and audio. If the technician is using a different HDMI port, such as one labeled "HDMI IN," the soundbar will not receive any audio signals.

This ARC port is part of new sound bars. Just installed the ARC cable and sound is great.
