Flash Player will not play YouTubes

I have windows 7 (64 bit), IE 11 (ActiveX) Flash Player 23.0.0.162.  Whenever I try to play a YouTube video I get a message that I need Flash Player installed.  When I check the Flash Player installed I get the 23.0.0.162.  I have uninstalled it (several times) and reinstalled but still will not work.  I have searched the internet for solutions and followed all suggestions - none work (by the way - all solutions are usually dated 2013 or before - nothing current).  I went to Adobe support and followed suggestions there but nothing worked.  I notice that when examples come up for the solutions they indicate IE 9.  Nothing for IE 11.  I have exhausted many, many hours in searching but nothing works.  I should add that YouTube in Chrome will play but without sound.  Spent many hours trying to get sound but nothing works there either.  I notice that all ads on the interest will play with sound unless they are YouTube based.  Some time ago I was able to put YouTube in my Compatibility setting and they would play ( even though I would have the message at the time of the YouTube screen that I needed to install Flashh Player) but that does not work anymore.
