It's important to note that the change only applies to the Web Audio API.
However, the unintended outcome of silencing web games has prompted Google to temporarily remove the autoplay policy for the Web Audio API, which is used by many web games.
Google says the autoplay policy will be reapplied with Chrome 70 in October, giving developers a chance to rework their projects' code to support the new API.
In the Chrome forum, John Pallett explained how Google updated the latest version to "temporarily remove the autoplay policy for the Web Audio API", writing that the change does not affect most media playback on the web, as the autoplay policy will remain in effect for video and audio. "If you are honest in your claim that the side effects of the policy were unintended and unwanted, you should commit-in clear, straightforward language-to finding other alternatives which do not break vast swathes of cultural work that was developed and distributed on the open web".
Google rolls back Chrome update after breaking browser games
But the change is coming back: by October 2018's Chrome 70, the "no unwanted noise on web pages" policy will again come into force.
The developer community has made their frustrations clear and the hiccup has found its way to the CRBug tracker and the folks at Chromium have taken notice.
The autoplay-video blocker is created to fix one of the greatest problems of the Internet: autoplaying videos on websites. One of this release's features was its ability to block web pages with auto-playing audio. Some requested user interface elements that would allow people to control how autoplay content is handled in Chrome, while others simply wanted their games to play their usual variety of music and in-game sounds.
Killing off autoplaying adverts in Chrome is a wonderful thing and has brought peace and quiet to many a browsing session, unless you are someone who likes to play games in your browser.
The autoplay blocking is an example of how browsers are getting more assertive on behalf of users faced with pushy websites.
