So does the digital signal carry some "volume" command within it? I can't think how else that would work.

You just change the bit stream...

way to keep on topic everyone, haha. I don't really care actually, this was just one of my fun threads, so have at it, it's all yours.

You change the digital stream so the amplifer will see a lower volume. You can play quiet soft music through the optical, and you can play loud rock music. So it is possible for them to manipulate the data going to the amplifier.
