I’m experiencing this same behaviour on two different computers now, so I thought I’d ask what is up. Playback suddenly stops, and RAATServer logs like this:

I'm running the latest 1.3-276 build of Roon Server on Linux.
The machine the logs are from, is an Intel Atom 520 running Ubuntu 16.04.3
I've also tried an AMD E350 running Ubuntu 17.10.
The DAC is a NAIM Dac-v1 connected via USB. Is this message indicative of something that is off between the computer and the DAC?
Linux keeps saying:
[ 1920.295795] usb 1-3: 2:1: cannot get freq at ep 0x5
[ 1920.299303] usb 1-3: 2:1: cannot get freq at ep 0x5
Happens very regularly, after playing for 5-10 minutes.
Hi, @Adam_Skogman, thanks for the report! Could you please describe your whole setup (Core, Storage, Network Topology)? Because the problem you wrote about can be be caused by different things. So, to narrow down the area of our research, we need more information from you.
My flac files are on a NAS (Asustor), connected via gigabit ethernet.
Both RoonServer and the RAAT endpoint is on the same linux machine (installed using the easy install server script).
Since I had just moved the roon library onto the machine (in both cases), the audio analyzer was running. In fact, since I saw it in the logs just when the system was trying to pre-buffer the next song, I turned analyze-on-demand off. That actually helped. My assumption is, the NAS is slow in delivering the file, so while waiting for auto-analysis, the whole chain times out ( there’s a 10 second timeout).
Ideally, the server should stream first, and not get hung up on analysis. Or pause the player. The fact that the player times out, on repeated dropped samples, then resets, is a not ideal, since the music shouldn’t stop
Glad to hear that you’re fixed by now, @Adam_Skogman ! I might suggest a workaround here – turning Audio Analysis’s max speed during the night, when you don’t use Roon, and most of your library will be analyzed during this time. Actually, Analysis is the procedure that takes place only once, so in the future you won’t be experiencing this behavior, and there will be no need for Roon to use analyze-on-demand option.
Thanks for your patience and sorry for the inconveniences here!
We can take a look at this, but background analysis is designed to be pretty aggressive, as a number of features (like volume leveling and waveform display) depend on it, and the goal is to get the collection analyzed as quickly as possible.
I agree that this shouldn’t be causing dropouts, but when we hear about dropouts during the initial analysis it’s usually because people are running their Core on an underpowered system. Assuming your Core is running on a device that meets our recommendations, I would be more inclined to think this is related to your storage configuration, or the network connectivity between your Core and your NAS.
Anyway, we’ll discuss – thanks again for the feedback Adam!
