I2S cable from rs130 to Denafrips DAC greyed out on inputs / outputs

Sorry if this has been asked before but I just purchased an rs130 and trying to connect it to my Denafrips Pontus 12th-1 DAC but the i2s is greyed out on the input / output screen. Am I doing something wrong? If I can’t get to use i2s which would be a disappointment is there an alternative recommendation? Many thanks

I have the 150b connected to Pontus ususing a type a usb to dvi cable. Make sure you choose type a mode

Hi thanks for the reply. My r/s 130 has a USB type A connector and the Pontus 12-1 has a USB type B connector. I don’t see a DVI connector on either machine. Can you please clarify.
Thanks

Both of them have type A I2s configuration. Get you a hdmi to dvi type a cable from Amazon. That’s all you need.

Sorry for my ignorance, newbie here. Then the connection is DVI out Rose to HDMI in Denafrips or the other way around?

Yes rose dvi out to hdmi in denafrips. It should work. I have the Pontus 2 12.1 and it worked. Get the shortest cable possible

Hello could you pls tell me what 1-0-0 you choose for your pontus ??

@elmostro thank you!!!
