if I may nitpick the current impl (testing on desktop firefox), with autoplay disabled, the volume icon shows as muted but unmutes when play is pressed.
if I want to mute a video before playing it, I have to click the volume icon twice - the first "unmutes" it (a nop), and the second mutes for real
simply an observation; from my experience, desktop users often prefer no autoplay & frequently rely on volume sliders in videos
I do really appreciate the quick response to the volume slider requests & even making the scale properly logarithmic!
I don't mind it sometimes, and at least it starts out muted (just a bit more data but that's not a big problem at home), sometimes it really is more convenient.
Volume sliders are an absolute must though, since I often have other audio in the background, such as a Discord call or a game.
