I have a H20 receiver with RC32 remote and Sony surround sound system. I have my remote programed to control the surround sound receiver. The problem I have is when I want to adjust the volume I have to switch the remote over to AV1, adjust the volume, and then back to Sat. Is there a way I can use just the volume controls without switching back and forth? ie. Like how the volume can be setup for the TV without switching to TV to control the TV volume. Thanks in advance.
