A family member recently asked me to help them out with some difficulties they have been having with the receiver. For some reason, I haven't been able to figure it out, but I'm sure you guys know how to fix this issue, it's a fairly simple one.
He's having problems getting surround sound from all of his sources. For example, from his DirecTV receiver. All connections are via HDMI. He's receiving no response from his 2 rear channels and the subwoofer(and possibly the center). However, when running tests, all speakers give the test tone. Can anyone help me with this?
