I just got a HiBy R6 2020 portable player to use as a source. It came with a USB to coax cable. I also got a convertor box to plug the coax in and then output to optical. I tried plugging the optical cable that I have into the digital 2 input of my H800, then switched the input using the RUX controller to digital 2, but I'm not getting any sound. The light on the other end of the optical is on.
My question is, does an Ai-Net cable have to be plugged in and connected into the H800 and then to something else in order for optical to work at all? If not, are there any other issues that might prevent sound output from when using the optical input? It works fine using RCA connection from my Kenwood head unit on Aux 1 of the H800, but I'm trying to bypass that. One of these days, I'll look to upgrade to a Helix DSP Ultra, but I've got to save up some pennies for that.
