Interpreting Roon Server Logs to Diagnose (Qobuz) Track Skipping

nquery · May 23, 2020, 5:16pm

Core Machine (Operating system/System info/Roon build number)

Roon Server on Mac Mini quad core i7, up to date, ethernet to router

Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)

1GB fibre in, Synology Router, ethernet to everywhere (a couple of 10G switches in there)

Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)

a. ethernet to Allo USBridge running latest Ropieee, USB to DAC
b. ethernet to Blusound Pulse Flex pair
c. ethernet to Allo Digione running latest Ropieee, SPDIF to DAC

Description Of Issue

24/192 tracks often skip to next track part way through song. Haven’t seen it with 24/96 or lower. 95% of content is via Qobuz but I think it only happens with Qobuz content. I play to a single zone Allo USBridge as per above or sometime I group both above and play to group zone. I believe that the skipping happens in both cases.

I am trying to interpret the Roon Logs to determine the cause of this - is it the connection to Qobuz to Roon core or is it networking issues after that.

The only thing I see in the Roon logs is that the endpoint buffers start decreasing from 100% down to 0% over the course of a number of seconds. And then the track skips. This happened on both endpoints when grouped.
All of this suggests to me a problem with the 24/192 streaming connection to Qobuz to Roon Server. But most of the time I do NOT get any error message on Roon Control app (on another networked device) and it just skips. Only very infrequently do I see the “Qobuz media is loading slowly” so I am uncertain.

Is there anything definitive in Roon server logs that helps one determine the cause of a track stopping play??? Here is the relevant section from most recent skip … where you can see endpoint buffers drop … is this because the source is not sending data or there is network issue? I assume the former.

Do you get the same behavior if the endpoints are not grouped?

nquery · May 23, 2020, 5:38pm

I believe so but I am running the same album that if often happens on to the single endpoint and trying to replicate and capture logs. Will update in a while.

There must be something in the roon logs that indicates why a track is stopped? The buffers draining from 100% to 0% over the course of x seconds suggests that inbound data to the endpoints has stopped. One can see at the end of a track - the RAAT endpoint buffer naturally drains as expected. But then it happens part way through a song and track skips. That’s not the cause in and of itself obviously. Is it because data from qobuz -> roon core has stopped/slowed or there is something after that? You would think there would be something in roon server logs …

nquery · May 23, 2020, 6:54pm

ok so i just got this while testing the single endpoint and it happened at roughly the same point in the same track as above to both endpoints (0:47) … but this time I got an actually error in the logs. Still trying to interpret the error/stack trace.

Of course I play it again and it’s fine.

So a quick grep of RoonServer logs shows that I was also getting this error to a 3rd endpoint in a different room a few days ago, when playing just to that endpoint. Also an Allo device running Ropieee connected via ethernet to the Roon core via router.

Can Roon support clarify what the below error means? does it imply a problem parsing the upstream streaming feed from qobuz or a problem with sending data to the endpoint? The first exception in Sooloos.Media.StreamingMediaFile.Read suggests the former to me …

These errors always seem to happen before a given streaming file has finished cacheing as per ‘grep streaming-std RoonServer_log.txt’. The first log above did not have this error, but again, the streaming file had not finished reading/cacheing. So maybe it just timed out instead of creating what looks to be a data error. Along with other similar reports like Tidal playback randomly skips to next track part way through playback, and the nature of the stack traces, I think this has to do with the connection between my roon core and Qobuz.

I have restarted my router, disabled EEE (energy efficient ethernet). I have a pretty vanilla setup and speed tests from the roon core server show 2 ms latency, 800Mbps + down, and almost 1Gbps up. Weird …

Hello @nquery and thanks for the detailed information!

have you tried local content? Let me know if you see the issue here too!

Also, are you having this issue when playing to system output of the core? Have you tried another device as the core?

Hi,

No it doesn’t happen with local content.

I have not listened to the system output on the core as it sits in a closet. Nor have I tried a different device as the core.

But that aside, and as per the title of my post/thread, why is it so hard to get information out of the Roon Server logs instead of trying this, that, and the other? Do the error messages I posted not specifically point to where the issue is occurring in the chain? Does Roon support not know how to interpret log messages? This is my frustration … surely the logs would indicate where to look for problems instead of trying all sorts of different hardware setups …

Regardless, I am sure the issue is with the stream from Qobuz to RoonCore failing for some reason. So I will be moving the core to a different location in network next to the router connected to the outside world to see if that helps. If not then maybe I will try another device or outboard nic.

Thanks

Update.

I tried to core system output and it still occurred. Clearly on the inbound side.
I moved the core server from an internal switch to directly connected to my externally facing router.

That seems to have resolved it. Suggesting possible packet loss/issues on the switch.

I still don’t get why Roon support/dev can’t interpret a stack trace/exception and point clients in the right direction … in this case, the exception clearly seems related to retrieving the upstream stream. Seems like most support processes are "have you tried this or what happens if you do this … " but the server logs are always disregarded.

Hi @nquery,

I’m glad to hear that things are resolved here!

Regarding the logs, we definitely look at these, but often times they’re not the most effective way of troubleshooting. The logs that you shared definitely pointed to a networking issue, but they don’t tell us much more than that. When it comes to networking troubleshooting, we find that practical troubleshooting is typically more effective than making guesses based off of the logs.

Understanding if things happen with local content, other endpoints, etc help to clarify what it might be. You have our apologies for the inconvenience, and I definitely appreciate the feedback here.

Happy listening
-Dylan
