So here we go. My friend has since upgraded his old Denon receiver to a Sony STR-DH590, and it's hooked to a TCL 4K TV. But he runs down how he made it work in his post to me which I copied below. And I did not recall correctly the path he had gone before, as you will see. You should keep in mind that while your desire to use the headphones and speakers at the same time is doable, it's sorta non-trivial. Post follows.
"I no longer have (OK: "use" - it's in the closet) my Denon so I'll have to pull this from memory. And it was done with the help of the TV - there's no way to do it with the amp itself.
AIR, I hooked up the optical audio out of the TV to optical splitter. Ran one of those back into the amp, and set the amp to get all its audio thru that optical in.** DenonThe other branch I ran to a optical-analog converter. The analog out of that ran into a little powered chair-side amp, into which I plugged my head phones.
You could plug in a blue-tooth transmitter to that amp instead, and then use bluetooth headphones, provided you pay for the fast-response pair, or you'll suffer from audio lag.
All this needed because of limitations of the Denon and TV.
** the problem with that setup is that the optical was linked to only one selection on the Denon, and besides the TIVO, I also have a DVD player, a CD player, Apple TV and an XBox (which I never use).
To get around -THAT- issue, I stopped running the equipment thru the Denon, and instead ran it all to an HDMI switchbox. The out from THAT went to to a HDMI splitter. One of those to the TV, and the other to HDMI to optical converter. That went into the optical-analog converter, mentioned above. FINALLY, we could choose any device, and have the audio go the the amp and/or the headphones.
Not exactly a simple setup!
The new amp and new TV are much more simple: The TV has a headphone out, so I just go from that directly to the headphone amp, which I continue to use because of multiple outputs with individual volume controls.
I'm also no longer using the bluetooth headphones since they didn't block out the sound from the "real" speakers, when my wife was also watching. Now I'm using Bose noise-cancelling headphones instead. All is finally good.
