What are the common reasons HDMI sound is not working on my TV?

There are several common reasons why HDMI sound may not be functioning properly. One frequent cause is incorrect audio settings on either the TV or the connected device, such as a DVD player or gaming console. If the device output is set to a format that the TV doesn’t support, it can result in no sound being produced. Additionally, a faulty or incorrect HDMI cable can lead to audio issues, as sound signals may not be transmitted effectively.

Another possible reason can be related to the TV’s firmware. Sometimes an outdated firmware version can cause compatibility issues with HDMI devices. Additionally, if there is an issue with the HDMI port itself, such as physical damage or dirt accumulation, it may result in poor audio transmission. Checking these components can often help to pinpoint the issue.
