I have an ONKYO HT-R592 receiver. When the source is set to AM/FM the volume responds normally, but when I switch the input source to CBL/SAT to hear the TV through the receiver or the DVD source to listen to a movie in surround sound (or any other way), the same volume setting I had for the AM/FM is now too low when I switch to another source (CBLE/SAT, DVD, etc). Why is this happening and what can I do to fix this issue? Thank you
