David, I'm curious - how is this "user technique" of the user turning down or muting the volume of their user agent in their OS any different from another "user technique" of the user having their web user agent enlarge the content on a web page (as a mechanism for meeting SC 1.4.4 Resize Text)? In other words, how is G142: Using a technology that has commonly-available user agents that support zoom <http://www.w3.org/TR/2012/NOTE-WCAG20-TECHS-20120103/G142> any different form a potential technique like: "Using a technology that can independently adjust or mute user agent volume levels"? Both are "user techniques" rather than "authoring techniques". And both tend to always work (though both should be tested; I can imagine some hacky ways of bypassing OS-level volume settings using downloaded native code).
