Sonos output only 20 seconds

[Pasi_V]

Hi

I have new setup with core 1.7 build 528 and controller in Windows 10 and couple of Android 10 devices.
Core is running in Centos 7.* and kernel 4.4*
I can add my local files in NAS and connect to Tidal.
But when playing anything to any of my 3 different Sonos play stops after about 25 seconds with notice “roon lost control of audio device”. Playing continues if I click play button again but same happens after 20 sec.

All devices are in same subnet and core, one of Sonos and Windows are wired and rest in wifi. I have added ports 9003/udp 9100-9200/tcp in linux firewall and also in Windows roon.exe and raatserver are allowed to public and private.
Rebooting devices has no effect.
Only when playing to windows pc speakers it works normally.

This is from core log file when this happens:

Hello @Pasi_V. Do you by any chance have your Sonos system configured to use SonosNet (I think it’s also known as “wired” or “Boost” mode)? I had similar problems using Roon with Sonos devices configured in that mode. Having switched the Sonos system over to using “wireless” aka “Standard” mode, Roon has been able to stream to my Sonos devices with very few problems.

[Pasi_V]

Hi, my Sonos is connected to my normal WIFI. I am not using Sonos internal network nor bridge.
Controller(or zp90) has physical ethernet cable and Play’s are in normal wifi

Hi @Pasi_V,

In the log file snippet you posted, it looks like you’re playing a TIDAL stream. Can you confirm if this issue affects both TIDAL and NAS content? Does the TIDAL web player (listen.tidal.com) work as expected on your end?

@Pasi_V

All devices are in same subnet and core, one of Sonos and Windows are wired and rest in wifi.

What is your network setup like? What is your model/manufacturer of your router? Are you Sonos devices connected directly to the router or to an access point/range extender?

[Pasi_V]

same issue if playing from Tidal or NAS.
My wifi access point is Cisco Aironet 1700 series and it is only working as access point. All “intelligent” stuff is happening in pfSense.(DHCP, bind DNS, LAN/WAN firewall…)
All physically connected devices are connected with Zyxel nonconfigurable switches. All wireles devices are connected to Cisco.

This setup has not changed in any way in last few years and Tidal and Spotify works fine with Sonos using native sonos app or directly from Tidal and Spotify.

Only new component is Roon server runing in Centos.

Hi @Pasi_V,

If you try temporarily hosting your Roon Core on the Windows 10 controller and have the controller connected using the same Ethernet cable, does the same behavior occur? That way we will know if this is a Core issue related to CentOS or if something on the network changed.

[Pasi_V]

Hi, I just tested and issue seems to be related to Sonos.
I changed core to Windows and all Sonos skpeakers were found and enabled, but when tryin to play it fails again “roon los connection to device” error.
I tried to play Nvidia Shield Chromecast and that works fine on both cores.

Here is log from Windows:

It seems if I group 2 Sonos together than it plays OK , but after ungrouping same issue returns

[noris]

Hi @Pasi_V,

Are you using the newest Sonos firmware? Were there any changes to your network setup or how the Sonos devices were connected when this issue started occurring?

I know you mentioned you rebooted some of the devices, but can you confirm you rebooted the Network Gear, the Core and the Sonos devices themselves as well?

[Pasi_V]

Yes I reeboted them all and changed core back to Centos. All Sonos are updated to lates version.
I did some testing with grouping again and seems like it has now effect on this. Device loose connections grouped or not.

But then I disabled firewalld in Centos and then it started to work. After few songs played I enabled firewalld again and then dropping started again.

So it seems that there are some more ports that must to be open than these:
9003/udp
9100-9200/tcp

[noris]

Hi @Pasi_V,

It’s great news that you were able to narrow down the issue to the CentOS firewall. Please look over the following post for a more in-depth explanation on how to set up your CentOS firewall as this may help:

Hello @Noris, I found the problem, and the solution. tl;dr at the bottom of this post.
