I just increased the buffer back to 250 ms and so far it's OK......but I need to test longer.

Playing in DSD bitstreaming mode to the Dac or PCM?
Dennis in FL:
I have encoding and bitstreaming set to "none"
Awesome Donkey:
That means MC is converting DSD to PCM on-the-fly, which is a very resource intensive operation (one of the most intensive tasks MC can do, especially multichannel content). That might be the source of your dropouts, the Mac's hardware might not be powerful enough to handle that conversion on-the-fly, hence the dropouts.
If your DAC supports DSD (DoP) I'd try enabling DSD bitstreaming and seeing if the dropouts cease - I wouldn't be surprised if they stop.

Just tested with DSD bitstreaming here on a 2012 Mini with10.14.4, lots of memory and an ssd... No gapping noted
Dennis in FL:
I have a ESS Sabre32 Reference ES9018-K2M DAC chip (Supports PCM audio up to 384 kHz / 32-bit, DSD audio up to 12 MHz (DSD256 or DSD4x) ) on USB
I changed to DSD 1X (4X) didn't work) and DSD bitstreaming.....so far the playback is perfect. I need to give it more like an hour long test.
Previously I had Core Out (imac) toslink or the above to my receiver with none/none
