Thanks for digging these out!

Giving my own (and to be honest, currently limited) analysis on your
assessment:
* I think A8 (mute/unmute) probably doesn't need anything from the Audio
API — we can already handle it by disabling a MediaStream object.

* echo cancellation (F9) was specifically discussed during the F2F; the
current requirement asks whether this is something that needs to be
dealt only at the browser level, or also at the Web app level. If the
latter came out to be needed as well, then that would raise the need for
the Audio API. I'll start a new thread on that topic.
