I have tried both turning off the option that lowers other programs when others speak as well as doing the same within windows audio>communications. Neither has worked, whenever somebody speaks my youtube video's volume gets lowered. It does not show this in the volume mixer, but I can certainly hear that it is happening. This never happened with my previous version, but I have done a format and this is a fresh install of windows.
