Certain websites seem to have been able to override Google Chrome's "Mute site" setting.
This is apparent if you follow the below procedure to perform a clean test:
- Go to Chrome sound settings (chrome://settings/content/sound).
- Flip the switch to show "Mute sites that play sound".
- Make sure the Mute and Allow lists don't contain youtube.com or duolingo.com.
- Try playing a random video on youtube.com, followed by starting a random lesson on duolingo.com (which, by the way, does not require an account).
Both websites will appear to be muted when audio plays (icon with crossed speaker shown in right side of tab and address bar), but only the video on youtube will actually play muted, while the duolingo lesson will announce foreign words when you click on them and read foreign language sentences out loud as they appear on screen.
Duolingo.com is the only example I know of so far, but whatever they are doing to override this setting, other websites could potentially be doing as well.
Does anyone know what it is that allows e.g. duolingo.com to override this setting?
Or at least how to enforce the Google Chrome "Mute site" setting for e.g. duolingo.com (please assume that my use case requires e.g. duolingo.com to be muted, while other websites continue to play sound)?
Additional info: Right-clicking on the e.g. duolingo.com tab and choosing "Unmute site", followed by another right-click to choose "Mute site" will actually result in muting the website. But only until the next time you load the website.
