As per Carl’s request I am posting again.
I am relatively new to Roon and, for the most part, enjoyed it a great deal. Yesterday (Saturday January 30th) I’d been listening for most of the day with no problems. But around 4 p.m. (Mountain Time) I experienced multiple audio drop-outs. Some lasted a few seconds, others lasted so long Roon skipped to the next track. It was un-listenable so I temporarily disabled Roon and returned to a previous system/app (Naim) and everything worked fine. I’m back to Roon today and apart from one brief drop-out it has performed well.
My music sources are a local hard-drive (Naim Unitiserve), Tidal and Roon Internet Radio. The local hard drive holds approximately 250 albums. I have about 150 albums in my Tidal favorites.
My modem, located on the 2nd floor, is from my Internet provider (Telus - Calgary, Alberta) - Model T3200M - and is less than 2 years old. Apart from the Roon issues, all other Internet functions work fine.
My hardware: Roon Nucleus (using version 1.7) connected to my home WiFi via ethernet to my main router (Airport Extreme) located in the 2nd floor room near my modem. My audio system is on the main floor. It consists of the Naim Unitiserve connected via ethernet to an Airport Express. My Roon Ready endpoint (a Lindemann Limetree Bridge) is also connected to the Airport Express via ethernet. The Limetree Bridge is connected to my Naim ND XS5 (used only as a DAC) via a coaxial cable. I control Roon on my iPad Air purchased a few months ago.
