I recently purchased a Denon AVR-X2800H receiver to use with my Samsung Smart TV. AnyNet is enabled - passthrough is enabled on my Samsung TV (QN65S95BAFXZA) and the Roku Ultra. The Roku will power off the TV and the Denon at the same time, but will only power up the TV. When I remove the Roku, the Samsung remote will turn on the TV and the Denon, but when I connect the Roku Ultra, the Roku remote (and the Samsung remote) will only turn on the Roku and the TV. I have to use the Denon remote to turn on the receiver. Any help is greatly appreciated - I am running out of Tylenol.
