Or maybe it is me!I am trying to set up a generic activity which would allow me to listen to iTunes through my Denon receiver. I have the Harmony 650 and the activity works with the exception of the volume control. I have taught power on and off through the old remote and the 650 says it learned the volume up and down but it doesn’t work. I have also assigned the unit to use volume up and down as up and down. Anyone have an idea how to get volume working for this activity? Thanks
