Indeed, so I think these new SCs are different, they are asking the author to do (or avoid) certain things so that the user-agent side can work. So:
- “Mechanism is available” means one or the other, the user-agent supports it (accessibility supported) or you provide something.
- “Support X” means enable the user-agent to work properly.

Just on that case (not the broader point), is there a keyboard method of muting a tab? I can’t find one for Chrome, only right-click on the tab seem to bring that up.
So the broader point would be that I’m not convinced the user-agent aspect is accessibility supported for 1.4.2, so probably not, yet.
