Description of Issue
Irregular short pops and clicks while playing. This does not happen while playing same material from usb drive to DAC. My library is stored on a USB drive attached to the iMAC.
Also when looking at the Activity Monitor on the iMAC it shows the RAAT Server as not responding. Is this normal behaviour?
I have tried various settings within Roon, and the pops and clitches remain.
