Make sure you have the latest version of Chrome/Safari/Firefox/Internet Explorer installed. If YouTube videos still appear to play no sound on your computer running Windows 10/8/7 or macOS X/Sierra/High Sierra, here are 8 feasible methods for your consideration.
The primary step you need to do is to see whether the Sound Card on your computer is breaking or not. To verify whether your sound card is working well, you can go to another website to see if there is a sound produced in online videos. Or you can play your local media files in Windows Media Player. If other audio and videos play with sound normally except YouTube, then you can be sure that your sound card has nothing to do with no sound on YouTube videos error.
Sometimes, you can just take things easy rather than racking your brains to make it so complicated. Probably YouTube online videos produce no sound as sound has been muted on YouTube website. After you open YouTube videos online, take a glance at sound setting to see if there is an "X" label available. If yes, you just need to move the volume slider to whatever level you want.
Still, no sound played on YouTube videos after trying above two methods? It is time to check the version of your Adobe Flash Player. Adobe Flash Player is a plug-in for YouTube and other videos website. Any incompatibility happened to it usually result in no sound and even no responding to YouTube videos. If you are still applying the old version, just download and install the latest one to prevent no sound with YouTube issue from happening again.
Try using incognito mode. If you no longer see the error message, this means you may have an issue with an extension on Chrome or Firefox. If so, you can go to remove the faulted extensions from your browser by right-clicking on it and selecting "Remove from...".
Cached data and cookies may somehow affect the use of browsers if having not been cleared for long. Therefore, you should get to clear them up. There is a quick access for all browsers - pressing "Shift" + "Control" + "Delete".
Then, a "Clear browsing data" window pops up. You should check "Browsing history", "Download history", "Cached images and files" and "Cookies and other site data" options at least and hit the "CLEAR BROWSING DATA" button.
You should go check out whether the browser is set to be mute in Volume Mixer. Right-click on the "Speaker" icon at the bottom right corner of the desktop and then select "Open Volume Mixer" on the pop-up menu. Now, you should make sure the browser and the plugin sliders are not muted and are not at the bottom.
You should try whether other videos can play sound on Chrome/Firefox/Safari. If not, you may need to download YouTube videos to your computer and the enjoy them on a video player.
Last but not least, the browser may be the one to take the responsibility of no volume on YouTube videos. There are so many web browsers out there available for you including Internet Explorer, Mozilla Firefox, Google Chrome, and Safari and much more. If you play YouTube video without sound in Firefox, then you are advised to switch to Chrome, IE to see if the same error happens to other browsers. If so, it is time to update your web browser.
In addition to the case above, many have reported that YouTube can play video but no sound/audio on iPhone/Android. If it happens to play no sound on some YouTube videos, that may be something wrong with these videos.
However, if YouTube plays no sound on all videos, you might be encountering a YouTube Sound Problem. In such a case, there are 6 possible solutions you can try out.
First and foremost, you should ensure that your Android or iPhone is not set to mute at present. For iPhone users, you should check out whether you by accident toggle on the "Ring/Silent" button. Also, you should turn up the volume to see whether videos can play sound now.
The YouTube sound problem may be caused by a system glitch temporarily, which can be resolved by a fresh new restart. It's always strongly recommended to reboot your iPhone or Android when unexpected issues crop up. I'm sure this may save you a lot of time searching on Google.
If you're using the YouTube app to watch videos but play no sound on videos, you may need to check out whether there is an available update for YouTube. Perhaps you just came across a bug that YouTube has come out with a fix in the software update. Otherwise, you might as well delete and re-install the YouTube app and see whether the YouTube sound problem is solved.
If you're using an Android device, you can try clearing the cached data on your phone. However, the steps to clear cache and data vary from device to device, so you'd better get down to your own phone.
If the above methods fail to help you out on the mobile phone, you may consider using an alternative to the YouTube app. That is to say, you can enjoy wonderful YouTube videos on browsers like Chrome, Safari, and Firefox.
If all workarounds end up in vain, perhaps it's a hardware problem with your speaker on the cell phone, which is nothing I can do. Therefore, you may take your iPhone/Android to an authorized repair store and get it repaired.
