I thought I would share how frequent dropouts were resolved for my Roon Core to Raspberry Pi 4 to Schiit Modi 3+ setup.
It was the USB A to USB micro cable. The bad one “looks good” but apparently was not good.
I changed to a different cable and all is good now, but not after spending many hours trying other solutions. I suggest a fast and easy swap of cables before getting into more involved possible solutions.
