Audio File Loading Slowly / Dropouts

[David A]

I switched to Roon from JRiver because I got tired of the endless upgrades and associated charges.
Once Roon was set up on my original system it was incredibly stable, better sound, and a better user interface.
Library analysis was completed, no excessive CPU usage.

Local files are played through NUC and input into Devialet using either USB or AES/EUB.

Problem is intermittent. can run through a whole bunch of songs just fine then decide to glitch.

The error message that an audio file is loading slowly tells you that there is a problem with a network connection to Roon. That problem could be occurring on a connection passing a signal to your NUC which is running Roon or it could be occurring on a connection passing a signal from Roon to a device elsewhere on your network. Neither USB or AES/EUB connections are network connections. They are digital connections but they aren't network connections. The error message Roon is providing is a message related to a Roon network connection.

Roon has to be connected to the internet so that is a network connection the message could be referring to. Roon may or may not be connected to your Devialet via your network If your Devialet is not connected to your network via wifi or ethernet, or if you are not using the wifi or ethernet inputs on your Devialet when the problem occurs, then the error message can not relate to network communication with your Devialet.

You have said that "Local files are played through NUC and input into Devialet using either USB or AES/EUB.". If that is the case then if the problem occurs while you are playing local files the error message simply can not relate to your connection between Roon and the Devialet. If you are playing local files via USB or AES/EUB connections then I would assume that you are also playing non-local files from sources such as Tidal or Qobuz over the same inputs to the Devialet. There is no reason I know of for playing local files over direct digital connections to the Devialet and non-local files over a network connection to the Devialet.

 If anyone is to have any chance of helping you find the cause and solution to your problem, we need more information. In particular we need to know:

1- is your Devialet connected to your network via ethernet or wifi? Roon has to be connected to your network but the problem can't relate to your Devialet if your Devialet does not have a network connection.

2- What inputs are you using on your Devialet when the problem occurs? If you are using either the USB or AES/EUB input, once again the problem can't relate to your Devialet because those are not network connections. If you are using the Devialet's wifi input then it is extremely unlikely that the error message relates to the Devialet. As advised in a previous response there is a long thread here about problems associated with this error message and, having followed that thread for several years now, I can not remember a single report of that error message occurring while using the Devialet's wifi input. That error message seems to occur only when music is being sent to the Devialet over ethernet, and specifically over a gigabit speed ethernet connection.

So please tell us whether you have a network connection to your Devialet and, if you do, whether it is a wifi or ethernet connection and if it is an ethernet connection what is the speed of that connection. Also tell us what connection or connections to the Devialet are in use when the problem occurs. Without that information it is impossible to tell whether or not the problem is even related to your Devialet and since the only connections you have mentioned so far are USB and AES/EUB it would seem that your Devialet can not be involved in the problem and the cause must lie somewhere in your network connection to Roon.
