What is HDMI?

HDMI is an abbreviated form of High-definition Multimedia Interface and is a connector that transmits audio/video data between an audio/video receiver and an HDTV.

As HDMI connectors have become common, the three composite audio/video connections are becoming obsolete. Here are some features of HDMI that make it better and more advanced than others:

  • As HDMI can transmit data faster, it is suitable for high-quality video games and home theatre.
  • HDMI supports 4K resolution video signals at a high refresh rate of 60Hz.
  • There is no need for two different adapters in HDMI as it can send audio and video signals. Further, the transmission occurs with no or very little data loss.
  • You can have a fantastic viewing experience with HDMI as it automatically configures various audio formats.
  • During signal transmission in HDMI, there is no compression. As a result, the signal quality of HDMI sound output remains intact, maintaining the data authentication.

  • A faulty playback device or non-functional soundbars may also lead to HDMI no sound problems in your device.

Why does a Bad HDMI cable cause no sound?

An HDMI cable is capable of transmitting multichannel audio through small insulated wires. You can also increase the channels by adding Dolby Atmos format and others.

You may face sound issues when there is any issue in these insulated wires, like being over-stressed, broken, etc. 

Most of the time, you will find that an HDMI cable is showing pictures, but there is no sound as audio signals do not transmit through it, and the reasons can be plenty.

Some can be bent or broken pins, loose or tight connections, coiled/tangled cables, missing compatibility, etc. A cheap HDMI cable can also create such issues.

However, that’s not true. A cheap HDMI cable will also give good sound and picture quality if it is not faulty. The only difference between a cheap and a high-quality cable is that of cable life; a high-quality cable will last longer.
