The device can operate properly with an appropriate driver, but if the driver is outdated or incompatible with the device, the latter may not perform properly and have problems such as no audio on YouTube. So it’s extremely important to make sure that your computer is using the right and up-to-date audio device. You can try the following steps to address the no sound problem as per your need or use Driver Booster to update the audio driver as this article has mentioned above.

1. Type and click “Device Manager” in Search.

2. Choose “Sound, video and game controllers” and right-click “Realtek High Definition Audio”, then select “Update driver” from the menu.

3. “Search automatically for updated driver software” is recommended. Then reboot your computer to see if no sound on YouTube problem is fixed.

Or you can update the audio driver with IObit Driver Booster:

Click “scan” and you can see the drivers which need to be updated in the “Outdated” list. Select “Sound, video and game controllers” to update them.
