How is "mute by default" different from "no autoplay" except that when users actually hit play, it would just start somewhere in the middle? (That sounds like an even worse user experience.)
It would be "no autoplay by default" instead of "mute by default".
the difference is that in the "no autoplay ever" case I would be not able to enable it if I wanted. "No autoplay by default" is the reasonable initial setting, while still giving users a choice.
