I second this post. I had the same problem with the MiniDSP SHD. I had bought the Dirac,mini DSP combo, primarily to add Dirac to my system, and that has worked great. However at the time I decided to get the Dirac/Streamer combo, because it was only an extra hundred bucks and figured what the heck, another streamer to play with. I had the same issues with Volumio and never use it.
I also have the CACXN 60 and had previously owned the Bluesound. The CA is a real bargain and I bought a second unit for a second system
