I'm not trying to do optical out, and not trying to use an external DAC. The Rock64 is running Linux (libreelec) and I have an audio output device for SPDIF. Is it as simple as taking an RCA jack and just connecting the tip to the SPDIF pin and ring to a ground pin? Or is a more sophisticated circuit required for some reason? Thanks in advance!
I'll answer my own question. Yes it works! Two wires and done!

For stronger driver output, you can cascade 3-4 7407 buffer driver.
