I bought one of these relatively cheap PSX SNAC adpaters on ebay (e.g. https://www.ebay.com/itm/385124081264).

On my Analog IO board the adapter works flawlessley, but on my Digital IO board (V1.2) it's not working at all.
"Normal" SNAC adapters work fine on the Digital IO board, so I assume it's the combination between the Digital IO board and the PSX SNAC adater.

Anyone any idea what the problem could be?

The Digiatal IO board has a jumper beside the SNAC port. Do I have to change this jumper to 3.3V?

Hey not sure if this will solve your issue, but I had experienced something similar with my digital io board. I missed a step in the install process. There is a switch(SW3) on the DE10-Nano that has to be turned on for the new digital io board. Fortunately I was able to use a small screw driver to flip it on by going through the fan opening. Saved the stress on the board from having to pull it off the DE10-Nano again.

No, that's not the problem. The switch is configured correctly. But thanks for trying to help.

Which “normal” SNAC Adapter is working?

No, it must be set to IO.

…and which Analog Board do you have?
A v6.1 Board?

//Edit
Where do you bought your digital board from?
Could you provide good quality pictures from the board?

//Edit2
Just tested my SNAC2PSX Adapter with my Digital Board 1.2.
No Problem here.
