Using Chrome to Block Sound from those pesky sites that start videos when you land on the page

A recent added Chrome feature is blocking the sound of sites.  This is useful when a video starts when you land on a site, even though you don't want the video to play.  I know this irritates me.  For example, the downloads.cnet.com has this on every download page, eg,  http://download.cnet.com/Malwarebytes/3000-8022_4-10804572.html.

The announcement of this feature is here:  https://blog.chromium.org/2017/09/unified-autoplay.html.  You can Google more about this feature, but the "bottom line" is:  To permanently mute site you visit where you don't want videos to automatically play,

1. Right click the tab for that web page, at the very top of the browser window, just to the left of the x on the tab. 
2. (Yes there is a drop down list!)  Pick "mute site" to permanently turn off the site.  
3. To turn the sound back on, go to the dropdown and "unmute site".

To improve web browser performance for those with slow internet, it would be nice if you could completely and permanently stop the video from playing using the same process.  I'm thinking this will come.  There is another approach that will do just that, but it is techie and is for all web pages.  Instructions:  http://www.thewindowsclub.com/stop-videos-from-playing-automatically-on-websites.
