I recently went to play a video on Youtube and I noticed there was no sound. I doubt it was the video as I have played it a few times before. After some searching, I found that other people were having the same problem. It turns out that Chrome was recently updated and with it was a bug that affects Windows users who do not use stereo sound (My computer was set to Quadrophonic).
Until this bug is resolved users can go into their audio manager and set their speaker setup to Stereo.
