Do any of the digital audio streaming standards (particularly those that pass over HDMI) allow a device to control the volume of the signal while still in digital format? Specifically, if I pass HDMI audio from BD to TV to RX, will the volume control on the TV affect the volume output by the receiver?

I would suspect not. But historically I've run Toslink from the source directly to the receiver. (I'm about to try HDMI.) And I've always been somewhat frustrated that the universal remotes I've used default to changing the volume on the TV, which has no effect. And I'd have to switch modes to control the volume of the receiver, then switch modes back to control the video.

I might invest in a Harmony remote if the TV volume can have no effect on the audio.
