I am looking for a Multiroom-setup via an mult-channel amplifier. I use the program J. River media Center for my music an a home automation protocol for the rest of the stuff in the house (KNX), i can use the output from a multichannel sound-card to feed the amplifier, but how do i control the volume on the amplifier itself? (via the computer) Some of them seem to have a "bus input", but what bus is it? Some proprietary protocol? Can i control the volume on the amp with IR, something else?
