Just on ‘youtube’ or is your volume icon missing on your computer, too? I had this happen on Windows 8.1 ... no volume control at all & I first noticed it when I tried to play youtube videos.
If this is your problem, here is the “fix” that worked for me:

Reinstall your sound driver? Reboot? Check to see if speakers are plugged in PC? Other than than I dunno.
If you’re using Win 7, 8 or 10, there is a trouble shooting feature that should identify the problem and fix it for you.
Go to settings and start from there.
Can you hear audio on other sites? Can you hear audio or video you have downloaded?
Have you tried rebooting? Checked your volume control?
You won’t like this, but I had a similar problem. I checked the speaker connections, switched browsers, rebooted, and all the normal stuff but finally had to take the CPU in to be tested. It took a new sound card to restore it . . . along with a lot of other stuff on the card which I didn’t need. They don’t sell just sound cards anymore.
Yeah. I’ve had that happen. - I just wait a day or two.
After that, it just comes back on its own.
Hope you get your problem solved.
I just wish the people that put videos up on Youtube
would not enter them where you only see the bottom
half of the screen!!!
Sometimes with a hardware issue, windows will lose track of the fact that it has a sound device or even a connected speaker. This can happen for various reasons. I've seen it happen quite often when a machine resumes from hibernate mode. sometimes it's the wireless card, sometimes bluetooth, sometimes sound. Usually the easy way to fix it is to shut down the machine and disconnect the power for 30 seconds (remove the battery if a laptop). Then boot normally and everything will come back. Give that a shot and see what happens.
are your speakers plugged in ?
I see your problem has been fixed by the help of FReepers. For future reference, sometimes youtube resets to MUTE automatically for reasons unknown to me.
All I have to do is hit the mute button to turn the sound back on.
