However, a common HDMI issue many users often face is missing audio. They can see the video on PCs and TVs connected with HDMI but can’t hear any audio to go with it. Thus, the HDMI video works but the sound doesn’t for those users. Are you another user who needs to fix the same HDMI audio issue in Windows 11? If so, try applying the fixes below.

Why is audio not working with HDMI?

Here are a few reasons audio is not working with HDMI in Windows 11:

Issues with the connection: Usually, it’s a loose or improper connection that leads to audio issues. Damaged cables: Whenever faced with this problem, you should check the cable for external damages since it, too, might be the reason the audio is not working with HDMI. Corrupt, incompatible, or outdated driver: When you have incompatible, corrupt, or outdated drivers, the corresponding device starts to throw errors. Reinstalling or updating the driver should do the trick. Misconfigured audio settings: The problem can also arise if you have the built-in audio device set as default instead of the one connected via an HDMI cable.

What can I do if HDMI is not playing audio in Windows 11?

Before trying any advanced solutions, here’s what you should do:

Try reconnecting your PC’s monitor with the TV by unplugging the HDMI cable and plugging it back in. Double-check that you’ve connected them correctly with the HDMI cable. One thing to note is that some HDTVs (high-definition TVs) have multiple HDMI ports. So, try reconnecting your PC with a different HDMI port on your TV if it has one. Also, check the condition of the HDMI cable before reconnecting. If you have an alternative HDMI cable available, try using that one instead.
