Which DAC config to use with Pro Ject Pre Box S2?

Hi! I got RP 3 with Pro Ject S2 Dac. Was using it happily for years, but SD crashed and had to rebuild the config. Now I can’t get Dac to work - it shows USB connection, but no sound or any info about audio type on the screen.
What config should I use for this DAC (i dont remember the old setting) - Generic I2S dac or something else?

Thanks for help!

I expect with “Project pre box s2” you mean the “Project pre box s2 Digital”?
If so, the DAC should show up under Playback Options, with i2s off, as output device in the dropdown.

Thank You!!!
