SPDIF to TOSLINK

[Nikolay_Po]

And all of the above devices operate with a power supply in the range of 2.7V to 5.5V.
Therefore, the "PLT133/T8" you have selected should also work with a 3.3V power supply.

Just arrived. Now I'm looking for a plug that fits into the socket of the board and didn't find much information, yet.

About a connector. Look for 2mm-pitch crimped wire three circuits connector, for example.
Just to prove a concept, I took old but brand new TOTX177A transmitter with 5V supply requirement and done this way:

P.S. letmegooglethat.com is just for fun, the question phrase actually is not obvious. Good luck!

Thanks, JST PHR-3 did it. I connected the transmitter already and it does emit light.

I connected my RockPro64 to a little amp by toslink and analogue cable. In Android I did get sound on the analogue output, but not on the optical output.

In LibreElec no SPDIF showed in audio setup and I didn't get sound via analogue output neither (but it worked using bluetooth).

I just looked very quickly in Archlinux and didn't get any sound at all.

Did anybody successfully try yet the SPDIF output and if so using which software?

Works in armbian buster. It showed up as Sink #2 (alsa_output.platform-spdif-sound.stereo-fallback) and I could play sounds to it using paplay. Toslink connection works also .
