I have XP and IE7. I use Google chrome. For no apparent reason I can no longer get sound on You Tube and some news videos on Google news. Some new videos work. Facebook videos seem to be fine. This also is occurring on my wife's computer, linked wireless to my main computer. This happened about 3 days ago and I'm at a loss. I am not a real "techie", but I can follow directions and learn.
I hope you good folys can help.
