Thinking of purchasing and have read about popping sound but if I understand correctly sticking with firmware 5.2b would fix that disabling power management. (will use as a DAC not portable device).
What really concerns me is the 1 second or even .1 second its muted before playback.
I would use with a Pi and a digione signature for time being eventually buying a device to handle playback with USB. My Roon library is everything from CD Quality flacs to DSD little constant pauses sound like it would be very annoying. So my question is how often does this pause occur with Roon.
