Did you not unmute the audio on the video? If you did, then check if the tab is muted. If it is not, then check the volume of your medium, whether it be a phone, a computer, or something else. Next, check if what you're using to hear it (headphones, speakers, etc.) is properly connect. Then, if you're using speakers or headphones that have audio adjustment options on them, check to make sure that they are unmuted and at an audible volume. If, after all of that, you still can't hear it, use a different browser. If that doesn't work, swap from what you're on (computer, phone, etc.) to something else. Then, if that still doesn't work, then either you need hearing aids or you're in a loud environment that drowns out the noise.
