Not unless you make secondary connections (usually L&R analog) directly from the devices to the TV. Then you'll have to connect their video to the TV too. You'll have one video input which gets the picture as switched by the receiver, and other inputs for each device. When not using the receiver the TV will pick what you're seeing/hearing, but the receiver will do that when it's on. It'll really complicate things.
Most people just forget about the speakers in the TV (mine have never been attached in the first place), and listen through the receiver full time. Is there a particular reason you don't want to do that?
