It was never supposed to be a “gotcha”, it’s just the obvious question that arises based on what you said. I didn’t think my ideas were clever. Your thesis when you started this thread was that there was an easy way to be sure that the mute is real, and you gave it. You sound like a person who simply can’t stand to just say “oh right, I misspoke” or even just “ah yes, I oversimplified”, so you act like obviously everything I bring up was implied all along, with a touch of rudeness as punishment. Even though, again, your point about there needing to be a zero-compression algorithm each made it seem like there was nothing else left to account for, even though there was.
I would not be surprised at all if there is a way to detect with high confidence whether the mute does what it should, and for all I know that has been done. I was really just wanting to hear what I was missing by bringing up the obvious questions that a non-security expert like me would wonder. You really have to ask yourself what you were even trying to accomplish with posting on this topic at all based on your reaction to those very simple, non-threatening questions.
