I think what we are thinking of is making volume control an optional parameter to enable/disable. That way we can give the embedder the ability to control that experience for the listener. Thoughts?
I don't want the embedder to control my listener experience, actually. That person knows nothing about my listening environment, and I don't want to adjust for their content. I realize this isn't such a big deal for someone that has SoundCloud playing in the background on their laptop while they do something else, but it's a total pain in the ass for anyone who works with audio professionally.
