OK this is going to sound a little off, but I'm not sure where to ask this. I cannot find the remote code ANYWHERE for my surround system. I'm thinking there's got to be a way to change this so I can use the TV volume to control it. Right now I'm using an HDMI cable that goes from my 722 to my sourround system then out to the tv (all hdmi). So as of this moment i have to use the volume for the surround system Is there a logical way that I can somehow use the tv to control the volume from the surround? I know that sounds crazy, but there's got to be way to do this?
