Using digital i/o's
Thought I'd post a screenshot of my settings just to see if I'm getting it right at the Scope end. I've set up the simplest project possible just to eliminate variables - just go's straight to my speakers via a channel so I can see if there's any sound at all.

I think this is right but there's no sound even though the light next to spdif presumably means there is a signal (confirmed when I unplug the cable from KORE as it go's out) - however where it says 96 is flashing and it seems to say 96 regardless of whether I have KORE's samplerate set to 44.1 or 96.

Pretty strange... I'd say it needs a bit of troubleshooting to find out if it's the Kore SPDIF out that's not working properly or your Luna's SPDIF in. Do you have another device with digital input that could slave to the Kore, to test it? Maybe you can take the Kore to someone else's studio to test it?
