Can't play DSD128 files


I am to this forum so would like to thank you all for unknowingly helping me put together an effective digital streaming solution.
My setup is RPi3+Digi+ running Volumio2 connected via coax cable to Chord Mojo. Synology NAS is the storage for high res materials.

All work great with all of file types up to 192/24 and DSD64. The problem is that I can not play DSD 128 and 256. I am getting a "Failed to open audio output " message and the system stops responding for a few minutes.

Any idea how to solve It?
