Automating muting for Web Audio has been delayed until Chrome 70 in October.
With the release of Chrome 66 last month, the browser began automatically muting sound on videos by default. The only problem is that this tweak silenced a number of web games and art projects, which weren’t built for the new feature. Now the Chrome team has rolled out a new v66 (66.0.3359.181 on all desktop platforms) that undoes the change as it applies to the Web Audio API specifically — but not for the <audio> and <video> HTML tags. The reprieve is temporary, however, as it’s planning to re-apply the feature in Chrome 70 which is scheduled for release in October. Read more
