Buffering pauses in MPD?

[Snoopy8]

I​​​​​​ noticed something today where some FLAC songs whilst playing on one of the DACs (Gieseler Gross) sometimes has momentary pauses, for a split second, like its catching up. But on the Denafrips this doesn't occur. Both DACs connected via USB same exact cables to the NUC.

But the Gieseler has no issues with DSF files.

Could it be the USB amenero firmware on the Gieseler? I could try installing a different firmware version.

Contact Clay and ask him what version of the Amanero firmware is the best for the Gross with a Linux server.  When I had the Gross, there was different firmware for Win vs Linux, but the problems related to DSF pops, not heard anything about FLAC.  I was using a SOtM SMS-200 Ultra then and there was an ability to set up the music buffer.  There is no equivalent buffer in SnakeOil.  

And running MPD in the NUC will hardly stretch it (which is what I use today, a NUC8I5BEH).  I am using CPUSet with 2 CPUs allocated to the player.  Not using process priority.  I do use RamDisk, so maybe you should do a test with this on both DACs?
