Welcome to the Roon Community! You have my sincerest apologies for the delayed response here, we’ve been dealing with a higher-than-usual volume following our release and we’re working as quickly as we can to get back to everyone.
If possible, can you take note of the name of the track you’re listening to when you hear the pop? If you could share a few songs this happens on, that would be helpful
I would also power cycle your core as well as your network router in the meantime.
