Several users have encountered Mac HDMI no sound. They gripe about videos playing silently. Well! Most often, these issues stem from various configurations and settings. Since you are reading this post, you must also be experiencing this problem. Thankfully, some fixes can assist in resolving the HDMI sound issue. Keep an eye on the screen and know what to do if there is no HDMI sound. So, let's dive into it!

Part 1: What's The Advantage Of Using HDMI On Mac?

The main advantage of HDMI on Mac is that it offers a fully digital signal that sends audio and Video over a single connection, simplifying things. Although HDMI and DVD are "completely backward-compatible," only Video, not audio, may be transmitted via HDMI when a DVI-equipped device, such as a Mac mini, is connected to an HDMI-equipped TV or vice-versa.

Part 2: Why there's No Sound When Connecting HDMI to Macbook?

There are some reasons why there is no HDMI sound when you are connecting HDMI to a MacBook. The first reason is that your system may occasionally have a bug that is creating audio issues. Another reason is that if you attach the HDMI cable to an already turned-on TV, the sound won't function. Moreover, the HDMI output does not have sound if the HDMI device is not selected as the default device.
