I thank you for trying to help but this has nothing to do with the media player on my system nor my sound card since saved video and music files all play fine. It is only the sound distorted on SOME embedded videos on all sites. I have the latest flash player so that should not be the issue. If ALL videos' sound did not work, I could see the possibility of some issue with my hardware/software, but that is not the case.
Also, it seems like once in a while,  the same video is OK if I try it again later. That could mean a new system process running intermittently in the background could be the culprit. I will live with this glitch for a while and see if it somehow sorts itself out.
It is a possibility that an installed program or process is having an issue with 8.1
If it gets too annoying, I may spend the time to shut off software/processes one at a time. Having troubleshot sound issues in the past, I can tell you that one never knows what can cause the problem.
I do not want to go back since 8.1 is noticeably faster.
