Does HDMI carry Audio? How to fix HDMI sound not working

We are living in a high-definition world, and obtaining the best image from the best gear, including the cables that connect your entertainment system.

HDMI is becoming increasingly popular in many areas, and you can find it on various devices. It is one of the most desirable connectors for HD video.

But does HDMI carry audio? Let’s get answers through our article!

Does HDMI Carry Audio?

All HDMI cables can transmit audio

The short answer is Yes. All HDMI cables can carry audio, ensuring your media is accompanied by all the sounds you expect.

Although the HDMI cable is known for its superior video quality transmissions, it can transmit audio data in the same cable. 

Like image quality, the more advanced your HDMI cable is, the more in-sync and sharper audio quality you can get. Since HDMI 2.0 and 2.1 came out, the number of channels we can transmit is up to 32.

If you choose an HDMI cable that delivers fewer capabilities than the device you connect to it, you’ll end up with a lower audio quality than expected.

Therefore, you need to consider what audio quality your device is compatible with to connect it with the suitable HDMI cable, allowing you to get the highest quality audio possible.

What Does HDMI Carry?

HDMI can carry both video and audio signals

Things that HDMI can carry include video and audio signals. One of the factors that makes it so popular is that it can transmit high-quality digital video signals. 

It is also considered a digital replacement for the older analog video standard. More specifically, it carries uncompressed videos.

It is prevalent in giving presentations at work or delivering news feeds throughout small areas. 

HDMI is also popular in the entertainment industry. For example, it is easy to find HDMI cables mounted to a TV, allowing you to watch your favorite movies or enjoy live streaming of any event.

In addition to efficient digital video transmission, HDMI can also carry digital audio through the same cable. That way, you can have an organized look in your space or when you use your digital gear at every event.

The flexibility of HDMI cables also allows you to link your MacBook to another device if you want to play music. It also lets you connect a TV to a PC whenever you want to enjoy audio files that have been saved on your hard drive.

If you cannot connect two devices directly through HDMI, you can try to use an adapter to transmit audio signals from one device to the other.
