I have went through the set up multiple times adding my Polk Audio Sound bar 6000 as my AV reciever. the revue will not turn up and down or mute the volume not matter what. I even set it up and went to the user define keys and selected the plus and minus rocker keys and tried a manual learn from my polk audio remote to the revue. It says it took the cammands.. I hit save and doesnt turn up or down volume.. Delete AV reciever and re set up Pol Audio SB 6000 still nothing.. The Sound bar is pluged into the back of my Vizo TV but that shouldnt matter. I did tel lthe revue to use the revue controller to controll my AV reciever not my TV.. I have the TV muted using the sound bar via old remote.. Any ideas?? Thanks!!!
