The value we display for the rate comes from the clock controller chip. I would need to go digging in the firmware to confirm for sure, but I believe that the reason it shows 44082 / 44122 is just an artifact of the way that value is being derived for display, and doesn’t reflect an actual deviation of -18 / +22 from the nominal rate. This happens regardless of what the external clock source is (for example, this happens in my home setup using Dante) and is not generally accompanied by any problems in the audio. This isn’t related to the popping issue that the original poster encountered.
Ok, thanks for the info. I just updated to 1.2.254, but don’t have the time to thoroughly test my H9000 right now. I’ll let you know if I keep getting audible issues.
