I don't have a DSD DAC. Also, I don't work for JRiver... I'm just trying to help out a little.
The "no bars moving" might be normal now that I think of it. Any time you bitstream, MC doesn't decode the audio at all. So it probably isn't decoding it simply to send it to the spectrum analyzer. I'm just guessing, but it seems like that would be right.
I don't know why you're not getting sound with bitstreaming set to DSD. Have you quit and restarted MC? For many audio settings, that is necessary. Also, check the audio path to see what MC thinks it is doing: Player > Audio Path
The bottom row of that display should say what format MC is outputting to the DAC.
Maybe someone with more DSD experience can step in here and offer some wisdom I don't have.
Good luck to you.
Brian.
