Roon Synology and Sonos [Under investigation - "Open vSwitch"]

Hello @Support,

I am currently trying Roon as it could be a good solution to federate all my metworked sound equipment in my house.

Setup:

  • Roon server on Synology 1518 x86 using the spk provided
  • Roon controller on a PC
  • Roon bridge on few raspberry pi and one PC
  • Sonos Play 5
  • Sonos Play 1

Everything is working fine, except the Sonos devices which are not detected by Roon when the server is running on the synology.
If I run the server on the PC, I can detect both Synology devices.

The issue seems to be linked with the Synology package.
My network is flat (1 C-Class for all my devices).

Regards
Alex

@crieke I’m Sure Chris will drop some things to look for…if not maybe @support will be a handy tag

Hi, @Alexandre_Perraud, thanks for the report! Could you please give more detailed descripiron of your network setup? Are your Sonos devices connected wireless or using ethernet cable?

Thanks!

Hello Ivan,
My play :5 is connected using ethernet. The play :1 is connected using wifi.

Hi, @Alexandre_Perraud, could you please answer a few more questions:

  1. Colud please tell me if there were any Synology updates recently?
  2. Is firewall turned off on your Synology NAS? If it’s on, please follow the steps here, turn firewall off, and see whether it fixes the problem.

Thanks for your patience!

Ivan

  1. Firewall is turned off. I can reach my sonos using Airsonos on the synology (via docker)

Thanks

I just tested it on my Synology DS1511+ and the same DSM version. Could see both my sonos devices. (1x Ethernet, 1x Wifi).

Do you have a managed switch in your setup? Are jumbo frames, or link aggregation enabled?

Hello Christopher,
I have an asus router Jumbo frames might be enabled.
I will check that one and keep you updates.

checked and no jumbo frames activated. I have just completed the update of my syno to the last version.
The interesting thing is i can play music to my sonos via Airplay using Airsonos which is setup on a docker container running on the synology.
Is there a way to activate verbose logging on the application to debug a bit? I can also do a network dump if necessary!
Alex

Hi @Alexandre_Perraud ----- Thank you for the report and the continued feedback, both are very appreciated!

Moving forward, I would like to gather two sets of logs from you so our techs can take a closer look into what could be causing this behavior to occur. Please see below.

Log Gathering Exercise #1:

  • Please sned us a set of RoonServer logs from the the NAS using the instructions found here.

  • Please title the package: “Alexandre_Perraud-LogsNAS.zip”

Log Gathering Exercise #2 :

  • Please temporarily host RoonServer on the mentioned PC, note the time when the Sonos devices are discovered/used for playback, and then using the instructions found here upload us a set of logs.

  • Please title the package: “Alexandre_Perraud-LogsPC.zip”

Hello,
@Eric, I have just sent you the onedrive links to the zip files.

My sonos is 192.168.8.247. There are some references to it in the NAS logs:

Hi @Alexandre_Perraud ----- Thank you for the the follow up and providing the requested materials :thumbsup:

Confirming that both sets of logs have been received and are in our queue to be evaluated by a member of our tech staff. Once my report has been updated and passed back I will be sure to share the team’s thoughts/findings with you asap. Your patience is greatly appreciated!

-Eric

Hi @Alexandre_Perraud ----- Thank you for your patience while our techs have been reviewing the traces found in the provided logs.

Moving forward, our techs are still trying to understand what could be causing this issue to occur and have asked me to have you please provide the following:

  1. If possible, the team would like you to confirm that you are able to connect to the Sonos devices from via Synology without using a docker container.

  2. You mentioned in your report that AirSonos works from inside a container on the Synology. If you are able to get to a “terminal” on the NAS, could you please try running the following command and give us a print out of the window?

Command: ping 192.168.8.247

Looking forward to your feedback!

Hello Eric and roon team,
I finally solved my issue. It was due to the Vswitch function which was enabled under the network interface settings.
Everything is working fine now!
Cheers and Merry Christmas.

(The vswitch feature has already been on my list to test/investigate.)
