what do you mean, remote volume? Would be just putting a receiver in the middle, fix it? TV goes either HDMI or optical to receiver, and receiver goes rca plugs out to amp?
to be honest, I don't know what the previous homeowners did. Here is a link to what I have: https/riverparkinc.com/manual/mhsamp-06-cube-product-information-document/
thanks again, and I really am not dumb. . So there is a separate item called remote volume, different from remote control? As for the receiver, my thought was to have an audio out on the receiver , where I could plug into the rca plug on the amp. No?
