Common Reasons Why Facebook Audio Not Working

Facebook videos not playing sound can be due to several reasons. Some of them have been addressed by experts. The situations include when the sound is muted on your device or in the browser. Yet, the most common one is that the video was incorrectly encoded or was silent in the first place. In this case, the most basic solution to fix the issue is to play other Facebook videos and see if they have the same audio issues. Apart from that, you can also check Facebook's video volume control. When you hover your mouse cursor over the video, the control appears at the bottom right corner.

Solutions to Fix When Facebook Sound Not Working

Solution 1: Restart Your Computer

Rebooting your computer may sound silly and basic, but doing so can actually solve various problems. Especially if you've been using your PC for a long time and certain apps begin to malfunction. A restart, in all circumstances, resets the current state of software, and it could potentially solve when there's no audio on Facebook videos at the same time.

Solution 2: Unmute The Sound on Your Browser

Like Google Chrome and Mozilla Firefox, these web browsers allow you to mute sound from videos playing on a particular site. With that being said, this could probably be the reason why there's no sound on Facebook videos on computer. To verify whether the problem is within your browser, you have to check your browser's settings. Since most users use Chrome as their default browser, you can quickly check its sound settings by typing "chrome://settings/content/sound" on the browser's address bar. From here, make sure that the "Sites can play sound" is enabled.

Solution 3: Use Other Web Browser

If you have plugins installed in your current web browser, try watching the same video on Facebook in another browser. Some browser extensions can suppress the sound from tabs, while others may cause your browser to malfunction.

If the issue does not appear after playing the Facebook video in another browser, try deactivating all plugins in the prior browser and replay the Facebook video again.
