In this article, we will will discuss about the how to Fix ‘HDMI Audio Not Working’ Issue in Windows 11/10. In order to view content on a larger screen, such as movies or web series, you will need to connect your personal computer to the television using an HDMI cable. It may happen that the sound is not audible on the TV even though the video is being cast from the computer onto the screen. It’s not uncommon for the HDMI port to be broken, or the cable to have some sort of issue.
When the PC and the television screen are connected, certain bugs in Windows 11 can occasionally cause problems with the audio output from the HDMI connection. The computer running Windows 11 may have outdated sound drivers, which could result in interference with the HDMI sound output. Additionally, you have to make certain that the HDMI audio output is selected as the primary source of output on your personal computer. There could be some issues with the Windows audio services, which would explain why they would have stopped working.
What is HDMI?
High-Definition Multimedia Interface (HDMI) is the modern audio/video (A/V) interface. Typically, it connects audio-video devices. The first HDMI equipment was made in 2003. The HDMI cable is shown below. Consumer devices like DVD players, HDTVs, Blu-ray players, cable boxes, video game consoles, audio receivers, and projectors use HDMI technology.
While other A/V connections require separate cables for audio and video data, HDMI cables can carry an uncompressed digital signal for HD audio and video presentations. A two-audio, three-video analog component cable connection requires five cables. However, one HDMI cable can digitally transmit the same information.
Why Is Audio not Working through HDMI?
There are several causes of this issue. The issue may be with the computer, HDMI cable, or monitor or TV. The best way to test all three is to connect the HDMI cable to another computer. If there’s no sound, it could be the cable or monitor/TV. Try a different HDMI cable. If sound still doesn’t work, check the PC or TV/monitor. Other causes include malfunctioning, missing, or outdated graphics drives and PC software issues. These issues can be resolved with one or more of the solutions in the next section.
