I have a Pi2 with HiFiBerry DAC working perfectly with Volumio 2 (2.55) connected to a wired home network and accessing music from another Pi (3 this time) which is running Stretch and AssetUpNp server and a USB HDD for storage (accessed via Samba for file management).
I have added another Pi3 with a USB DAC (Arcam rPac) but unfortunately whether in 2.0 or 1.0 mode any FLAC that is 24 bit HR stutters and are ultimately unplayable.
Output device is set to “Arcam USB Audio 2.0”, I2S off, DSD direct on, 2mb buffer, 10% before play and Mixer Type set to None.
aplay results in:

Are there any tips towards getting HR files playable with this new Pi/Volumio setup
