I am using the e30 with a rpi4b (usb), running IDPi as a dlna renderer with Jriver media server. Everything works well. The pi is set to native DSD, with bitstreaming, sounds great. On a whim, I tried turning off native DSD to check out DoP and it didn't work! Just hiss.. The e30 works fine with Dop on my mac. So I tried a Sabaj Da3 with the Pi, It works in both native and Dop modes. Is there a configuration to add to the pi or some update that will give me dop? I'm not sure if I will need it to work on the e30, but I was thinking of adding a digione, which I would use coax to the e30. I would be more comfortable pulling the trigger knowing that DoP is working with all devices. Anyone having similar issues? Any help would be appreciated.Thanks
