Indeed. I've got a pretty big installation here with some stuff in one
part of the room - TV, PVR, satellite receiver - and the main audio
stuff at another. All interconnected unbalanced. It's also linked to
sound and vision in the kitchen so I can have the same thing playing
etc while wandering between the two. And no problems whatsoever with
hum. It would be a poor piece of design which has high levels of
nasties on an audio ground.

Try measuring one. Cable screen to mains earth either on AC voltage or
low current. It may surprise you. Mind you, if it's ALL Class II
equipment the return path to ground doesn't exist so you may get away
with it.

I obviously have. The only earthed component is the AV amp. Otherwise I'd
have hum ;-)
