There is more than Intel. Click my link, and you will see that RPi4 + HiFiBerry Digi2 Pro is an S/PDIF setup!
I have since went this route and I’m very impressed with the setup. May I ask, there are two outputs for the digi2+ using the latest image of LE. Does it matter which to select? Is it clock related because there are two clocks on this hat to take care of 44.1khz multiples and 48khz multiples. Or is it because there are two digi overlays?
Little confused, thanks again for the recommendation!
