No, Ben, I don't. And, as I understand it, this is impossible. Since we're
just passing through a digital signal to the receiver, it's all up to the
receiver to deal with it. In order to change the volume, we would need to
decode the audio, sample down the volume, reencode it, then pass it on to
the receiver. Maybe it's possible, but it certainly is not very efficient.
And, by the way, this is all just speculation. I don't really know how it
works, but my explanation made sense to me.
