But it would be good if users manually had the option to enable the audio input without needing a video signal. Also, I can't imagine that it saves significant energy.

Probably just another power user feature that manufacturers didn't pay attention to.

I was being sarcastic.

They in fact force you to have a signal which consumes more that if the display was blank/idle/shut off.
