YouTube videos without sound - Corrupt flash player? Help?

Hi everyone, I have a bit of a problem. I went on to YouTube this morning, trying to watch a video. Unfortunately, the video failed, and it wouldn't play. All I got was the ad in the very first frame, yet the video thought it was playing. I looked online, and it said that my flash player was corrupt. So I went and I installed flash player on my laptop again. I tried to play the video again, and it played. Unfortunately, there was no sound. I went through about five extremely unhelpful troubleshooting pages shared between Adobe and YouTube, and got no results. Pretty much, Google has kept saying it's my Adobe, and Adobe has kept saying that everything is fine with flash player. Could anyone help me? This is very frustrating.

               System: Windows 8 64 bit.

                   Adobe flash player: 32 bit installation.

                    Browser: Google Chrome.
