For whatever reason, I can hear sound for every ad that plays, but as soon as the game pops up, nothing. I've tried several different games, and none are particularly keen on playing any sort of audio whatsoever. Again, I can hear ad audio, but not game audio. For whatever reason it happens on Kongregate, too. I have no idea on how to fathom this.
@Purpleyoshi22 It's a long shot, but did you recently upgrade to Windows 10? If so, you can find help about known audio problems here: Driver Easy Windows 10 Audio Fix.
If this is not the case, can you post the browser you're using so I can have a look?
