The staff at Bryston helped with my USB output problem (hi-res files not working properly). An update of the firmware image to the internal Micro SD card did the trick.
HOWEVER -- Now I can't get Qobuz to work. It tries to play a file, and it even shows the cover art in MM. Then it just stops and blanks out the cover art. I'm thinking I have a wrong setting in Manic Moose.
What flags do I need to set in Manic Moose to get Qobuz to play properly?
