songsuk@

Is this reproducible only on certain Chromebooks?

Can you see any warning on the console like "An AudioContext must be created or resumed after the document received a user gesture to enable audio playback"?

So far, I checked the issue only on Kip and reks.  Will provide more info once check the issue on the other device.

Yes, there is the warning on console while playing "Candy crush saga".

Yes, this means the developers now have to construct AudioContext or call AudioContext.resume() upon the user gesture. It seems the game is served from a different domain via iframe.

mlamouri@
Do we have any public announcement or article about this change? I am also curious myself why this affects the desktop browser.

In the meanwhile, we might want to reach out developers to let them know the workaround.

+johnpallett@ for reach out.

Removing RBS as its not blocking stable and is likely a web developer fix. One possibility is that they need to simply delegate autoplay privileges to the iframe using allow=autoplay. We might want to check if they aren't already using gesture=media.

Labels: -Pri-1 Needs-Feedback Pri-3
Per #7, this is likely a web developer fix. Lowering the priority to P3 and asking feedback from developers.
