Welcome to the forum Jeff!
I’m pretty sure the display shows DOP when using Bridge 2 to play DSD files. Not sure about USB or other inputs. I wouldn’t worry about the display showing DOP (that does mean the DS is seeing the content as DSD) but the fact you’re getting static instead of music is obviously not right. What is your system configuration (Mac or PC or other, server software, control point software, connection type, etc.) Can you run the bit perfect test (look in the knowledge base for instructions and the downloads page for the files)? If any digital signal processing is going on, including even reducing the volume in the server software, DSD will not play properly.
