Description of Issue

Since build 923 I’m having drop outs when streaming Radio Paradise via my KEF LSX (KEF streaming) and SONOS Play:1 (Sonos streaming). No issues with streaming Radio Paradise to KEF LS50w2 (RAAT streaming) or Beoplay M3 (Chromecast streaming). Sometimes stream comes back after drop out, sometimes stream fully stops.
Streaming Qobuz to the KEF LSX and SONOS works fine without problems.

Here’s the output of the RoonServer log when a drop out occurs, and in this case picks up again:

Hi, @Kjeld_Kerssemeeckers, thank you for your post. Could you, please, answer the following questions:

  1. Do you have any issues playing other radio stations?
  2. Are you seeing issues in case you are trying to play both AAC and FLAC streams provided by Radio Paradise? Could you, please, specify the exact Paradise Radio station you are seeing this issue with?

Thanks!


Ivan

Hi Ivan,

  1. Yes, I have the same issue with other radio stations. E.g. this one: http://playerservices.streamtheworld.com/api/livestream-redirect/VERONICA.mp3 (Radio Veronica, MP3), or this one http://greece-media.monroe.edu/wgcm.mp3 (Jazz 90.1, MP3). Less frequent drop-outs with the latter though. Another FLAC radio station with drop-outs: Mother Earth Radio (http://server9.streamserver24.com:18900/motherearth). See log dump below.

  2. I’m having the issue with the Radio Paradise FLAC stream http://stream.radioparadise.com/flacm, the other FLAC stream https://stream.radioparadise.com/flac, the AAC stream https://stream.radioparadise.com/aac-320, and the MP3 stream https://stream.radioparadise.com/mp3-320.

By the way, I’m now on build 933. Issue still there.

Currently on build 943. Dropouts still happen. Seems to “auto recover” more often. But sometimes still hard stop:

Now on build 952. Roon is now totally unusable with KEF + SONOS streaming. Doesn’t matter if I stream radio or Qobuz. Streams stop all the time.
Just to repeat: streaming to Roon endpoint (KEF LS50w2) from same Roon server is working fine.

Some warnings I see in the RoonServer logs:

  • Track Stopped Due to LostEndpoint
  • [streammediafile] error reading stream: Unable to read data from the transport connection: Software caused connection abort.

I see the latest build is producing more logging, so hope you are getting closer to resolving this.

Hi @Kjeld_Kerssemeeckers ,

Thanks for the update here, and sorry to hear you’re still seeing this issue. Can you please provide some more info regarding your network setup? What is the model/manufacturer of the gear? Are the LS50s connected the same way as the LSX with the issue?

Hi Noris,

I’m now on build 970.

My networking setup is as follows:

  • LS50s are directly connected to Internet router/switch
  • Roon server is directly connected to Internet router/switch
  • Sonos are connected via Wifi AP (which is directly connected to Internet router/switch)
  • LSX are connect via desktop switch (which is directly connected to Internet router/switch)

In order to be able to enjoy Roon and my LSX speaker I am now running a setup where I’ve connected an USB->Optical bridge (SMSL PO100) towards the LSXs from my Macbook laptop. Macbook is connected to the same desktop switch as the LSXs. I direct sound then to this USB interface directly from Roon on my Macbook. All works fine, no dropouts.

Hello @Kjeld_Kerssemeeckers ,

Thank you for that information!

Since the LSX was connected to another switch, did you try to bypass the desktop switch yet and have them connected to the Internet router/switch instead? Or, if you are happy with this configuration and there are no dropouts, you can keep using the Optical Bridge to connect your LSX. Do let me know how you wish to proceed, thanks!

Hi Noris,

I will keep using the optical bridge. A shame though that the LSX have problems with Roon.
I will try again with future Roon versions!

Thanks for your effort.
