Depending on the TV model, one can claim to the TV that an A/V receiver is being controlled by the TV's remote. In this case the remote's Volume control can issue commands to an arbitrary A/V receiver.
Yeah this is what I do.
Only problem is, as PSS mentioned, if they are using the TV factory remote, they can't control volume then. Of course, with Samsung it's often a bluetooth remote so you're still SOL. Often times they use an Apple TV for streaming, which works well since the new Apple TV allows for volume control of the Playbar.
