I had a short disuccion with a friend today. He's how i can sum it up.

There is never digital output to speakers/headphones, even in a
digital TV. The processing is digital but the output has to be analog.
So, if the digital output is enabled on teh computer, the headphones
can't interpret the signal. Only the TV can interpret the signal,
amplify it and output it to its speakers through a Digital to Analog
Converter (DAC).

IOW, it's no use to try to figure why I can't get the sound to my TV
by testing the headphones jack.

That's the version I have too. No "port"  chooser.  See:

I enabled the Fallback option, which wasn't enabled. I have no idea
what "Set as fallback" is supposed to change.

All I want to do is send sound through an ***HDMI*** cable to my TV.
The S/PDIF wire between the motherboard and the NVIDIA card is
installed. I explained how it is installed in my previous message.
Make a search on J8.
