The specification from the client was, "I need some way to hear my TV better that doesn't blow out my wife and kids sitting alongside me also watching/listening [to a 5.1 surround system]."
Oh, I see. Your initial post made it sound like he was giving component specs. Got it. And this is NOT a rare problem. We do need a go-to solution.
The technical reality is that there's not a [cost effective] way to add duplicative analog or PCM-Toslink feeds from remotely-located source equipment to this Denon AVR, all of which output Dolby Digital encoded audio to the AVR via HDMI.
I'm tempted to say more info is needed, but... it also looked like the AVR was somewhere in the neighborhood of the TV. You have an added issue, which is the range of the wireless headphones. If your AVR is a hundred feet away....
Can the receiver send audio to the AVR amps while also sending it to the TV via the HDMI signal? If so, then an audio extractor near the TV, feeding a wireless headphone, might be the answer. I'm having some issues with exactly that right now. It looks like I haven't properly controlled the format of the audio part of the HDMI signal, so I sometimes get audio. Sometimes get silence.
As such, I need a device to take a switched, muxed output of the AVR
That would be the audio on the HDMI output
and convert or transcode it into some format that can be fed to a set of wireless headphones.
That's the audio extractor.
I asked about toslink/DD inputs specifically because SONY once made a set of wireless cans with DD-capable Toslink in, but they were long ago discontinued.
As suggested by Fred Harding, an HDMI Audio De-embedder on the AVR's Zone 2 HDMI output feeding a set of wireless cans with stereo inputs may be the best solution.
I like it even better on the main HDMI output, but mostly because that would put it right next to the TV without running any added cabling.
