Hi folks

I have a UFX II and i'm trying to plug a UAD Oxbox (guitar attenuator and cab sim) that outputs SPIDF out through the optical cable. I connected the Ox SPIDF out to the ADAT '1' in on the RME and could never get any signal.

I tried connecting another interface i have through the same cable to the same ADAT 1 and connected a source to that interface and the RME was able to read the ADAT input just fine.

I also connected the Ox Box to a Babyface pro ADAT in and it worked nicely

The only thing i tried and worked as a last resort was to simply plug the optical into ADAT 2 instead of ADAT 1 and then from the USB settings set optical 2 input to SPIDF.

Two questions:

- Is there no such setting for ADAT 1? that doesn't make sense but the software doesn't show a selection
- In my case where it worked, i expected the signal to show up in one of the ADAT inputs, but it's showing up under AES

Really appreciate any pointers this is driving my crazy and i worry the setup is subpar sonically because of this
