The file is stored on my Mac. My Mac is connected to my Roon via the Silent Angel and then on to my DAC that handles DSD files all the way up to 22.4 Ghz (1 Bit) files. I have no trouble listening to many other DSD files.
I hear the first few seconds of the files in 512 DSD but then get the error “Audio file is loading slowly”
I looked in my settings, and apparently I cannot select DSD playback up to 512. I am not sure why Roon will not let me select this resolution. Also, Roon will not let me select “exclusive mode” either.

I have lesser DSD files that work fine, but I think Roon is struggling with the 512 files, where is shouldn’t.
Your suggestion of putting the file on an external drive…the file is on my iMacs hard drive. The hard drive is connected to the Silent Angel which is connected to my DAC, so i think I am already accomplishing this.
Please noted that DAC supports DSD with “DSD Native” is required for you to play DSD music up to DSD256 smoothly. If your DAC supports DSD with “DoP” (DSD over PCM) mode, then the Z1 only support DSD music up to DSD64 (which means DSD128 or DSD256 is not supported in DoP mode).”
Bummer. I’m using VitOS (software from Silent Angle) on an RPi4, and it seems handle to native DSD512 just fine. Perhaps the limitation on the Z1 is related to hardware?
Edit: Wait…sounds like the issue is a missing native DSD driver in the Linux kernel for the particular DAC. Unfortunately, support for native DSD is not 100% consistent or guaranteed on Linux-based network to USB bridges.
Thanks David for your input. Strange thing is that the file will play the first few seconds of the file and my DAC shows it is in the right resolution. It looks like it is either an issue with the size of the file that Roon’s processing time is too slow or the processing time of my Silent Angel is too slow.
I do not think public Linux distributions recognize or support native DSD operation of it.
Therefore native DSD512 won’t work in your setup. DSD512 DoP is not supported either.
Your Roon Core CPU is also below Roon CPU minimum requirement.
You can ask your Roon Core manufacturer to see if they are willing to patch the Linux kernel for you.
In case there are Luxman D-10X / D-03X users using Lumin streamers, please contact me for a beta firmware that supports native DSD for these models. I’ve made the change many months ago but still have not got a confirmation about it.
