When you try it, make sure you are sending a PCM (stereo) digital signal from the STB, not a Dolby Digital signal. I've tried using a DAC with a STB only to find out that my STB can not be set up to output PCM. It only outputs DD, so it won't work for me.
Obviously it worked for you before, so your STB can output PCM. Just be sure it is PCM when you try the Northstar.
