Surround sound not working with new smart tv

I have a samsung 7100 series uhdtv that I want to connect to my 15 year old pioneer elite a/v receiver via digital optical cable. I’ve tried everything I know to do.
I cannot get the sound to come through my surround sound.

Clarification Request
Almost all Samsungs will not pass 5.1 sound.

You left out details but I would only expect 5.1 sound from OTA (over the air) channels, streaming (Netflix, etc.) and maybe, maybe content from USB media.

Remember the right setup? All sources go to the receiver with an optical link for OTA, streaming.

I’m streaming content exclusively through YouTube tv (and Netflix, amazon prime sometimes), and I have my optical cable
Connected to the tv (from the only optical output) and in the ‘tv/sat’ input on my receiver. I set the tv up to utilize the ‘digital/optical output’ but no sound comes through the receiver.
I tested the cable and it is working fine.
My concern is the age of my receiver and I’m also worried the tv may have a bad optical jack.

Then only more testing.

DON'T LOOK AT THE OPTICAL CABLE OUTPUT. Do you see anything if you point what would go into the receiver at paper? It's not a definitive test but one I do once in a while.

Also, try PCM.

More testing. You have to try a known good source then back to the TV. Be sure all firmware on all devices is current and you didn't do something like leave the optical end caps on (these are only there for shipping and discarded during install.)
