Question

Add new music library

We have a Brennan B2 unit (described as ‘a CD ripper, hard disk jukebox and complete audio system’) and have tried many many, times over several years (no exaggeration!) to play music stored on the Brennan hard drive through a Sonos One speaker in a different room - but with both connected to the same router by wifi. It has proved unbelievably frustrating and we have tried every solution suggested by either the Brennan or Sonos communities. We even sought speciality advice from Richer Sounds. Sonos does – most of the time – recognise Brennan as a music library and sometimes is successful in playing a track from the Sonos app. But, with maddening regularity, Sonos fails to play that track. The only source of music I can access on the Sonos system with reasonable reliability is Sonos radio stations and some others (e.g. BBC Sounds). Another workaround is to use the Brennan app and direct it to play specific tracks on the Sonos speaker. This also works sometimes – but not always. I am aware of the significance of DLNA and NAS and have ensured the settings are as recommended. And, yes, I’ve rebooted the system and checked passwords umpteen times ...

At one point, I wondered whether the problem was that the wifi signal was not strong enough, so we bought a Sonos Boost and a Sonos Connect. However, that has made no difference. To be honest, I have now given up.

The specific reason for this enquiry is because I want to access my music files in a new room, which currently has no speakers. If the Brennan:Sonos link worked reliably, I would simply buy another Sonos speaker and connect it into the same system. However, it doesn’t work reliably - so I don’t want to make additional purchases which will only work erratically. I would be better off cutting my losses and buying a cheap internet radio, which would be adequate to access BBC Sounds, but without any potential to play music from my stored files.

I am wondering whether there is any other way of playing the music library, currently stored on the Brennan hard drive, though a new Sonos speaker - and with a reasonable degree of reliability. Presumably it would involve copying the Brennan hard drive onto another storage unit and connecting that into the new Sonos speaker. But how? Through a hard wire (ethernet, perhaps)? However, I wouldn’t know where to start with this.

I would very much welcome advice from someone more knowledgeable than me!

Many thanks

Have you tried an Ethernet dongle to connect the Brennan to Ethernet?  It has always been the recommendation of Sonos that the music library be hardwired to the network, so trying this with the Brennan before copying the library to what is essentially another hardwired NAS might do the trick.

There are many past discussions here, I recall them but not the contents. I do think some people got it working.

I do seem to remember a link posted to an FAQ on the Brennan website….but not the details. As I recall, it was how to set it up to ‘talk’ to Sonos. There are lots of assumptions on my part, but as I don’t own one, they’re theoretical.

 Below captured via ChatGPT. The Brenan should be wired to your network via Ethernet. Also the Boost is not necessary in fact it may cause problems.

It would also be useful to configure a fixed IP for the Brennan on your DHCP (router).

If not the library will be 'lost' to Sonos should a different IP be assigned by the DHCP after, for example, a power cut/cycle or reboot (of either the Brennan or your router)...

You said:

At one point, I wondered whether the problem was that the wifi signal was not strong enough, so we bought a Sonos Boost and a Sonos Connect. However, that has made no difference. To be honest, I have now given up.

If you have a Boost your Sonos One is usually not connected to your Wi-Fi but to Sonosnet, an older and poorer performance connection than most modern routers. Removing the Boost and any other Etnernet connections from your Sonos and putting all your Sonos on Wi-Fi is likely to make your system more stable and reliable.

I am not sure what the Connect has to do with this setup as it is for importing or exporting music from the system to an external receiver, not for the music library.

Note that Sonos S1 requires SMBv1 and associated files. Sonos S2 devices require SMBv2 and above.

I am very grateful to everyone for trying to help!

In response to questions about my current set-up, the Sonos Connect is conected to the Brennan with phono leads; and the Sonos Boost is connected to the router (Fritz!Box) with an ethernet cable. The Sonos speaker is purely wifi. To be honest, I have tried most of the recommendations over the years (this has been going on for ages); indeed, at one time I tried simply using the Sonos speaker on a wifi basis, without using the Boost or Connect at all. Many of these set-ups work on a desultory basis but none are reliable over a long period. That is why I have largely given up.

For me, the question looking forward is: is there a different way of using the data stored in the Brennan hard disk so that a new Sonos speaker in a different room could access it on a reliable basis?

But, to repeat, I am most grateful to everyone who has responded and tried to help.

Are you confusing wireless with Wi-Fi? Sonosnet is wireless but not the same as Wi-Fi. It also uses older, less reliable connection methods than most modern Wi-Fi routers.

With the Boost, or any other Sonosnet capable device connected to Ethernet you are by default forcing all Sonosnet capable Sonos to disconnect from your Wi-Fi and reconnect to Sonosnet. The Boost is considered legacy, still supported but no longer sold making Sonos' opinion pretty clear.

Most folks find using their Wi-Fi more reliable than using Sonosnet. There are advanced configuration options available but you are almost always better served by the Sonos recommended all Wi-Fi setup.

Hi Stanley_4

Thanks for explaining about Sonosnet.

​@Gilzean, What model of the FRITZ!Box is it? Is there also a FRITZ!Mesh, or are you using wireless extenders from another manufacturer?

Hi Smilja

We have a FRITZ!Box 7530 AX, meshed with a FRITZ!Repeater 3000AX.

​@Gilzean, Then we should first clarify whether you want to continue using SonosNet or switch to the router's Wi-Fi. My system works flawlessly via SonosNet, but nowadays Sonos also works quite well with FRITZ!Mesh.

As mentioned by ​@Stanley_4 you are most definitely confusing; or rather not understanding, the difference between the SonosNet and your home WiFi.

Once the Boost or any Sonos speaker is connected to your router via Ethernet the SonosNet is activated and ALL Sonos is removed for your home WiFi and onto the SonosNet. Simply put you have two networks. The difference being that other home wifi devices cannot see/connect to the SonosNet.

To resolve the issue do the following in the order listed:

  1. Unplug all Sonos including the Boost
  2. Remove Ethernet cables from the Boost or any Sonos speaker
  3. Remove the Sonos App from your device
  4. Unplug the Fritz Repeater
  5. Reboot your FRITZ Box and and let it come back
  6. Plug in the Fritz Repeater and let it connect to your FRITZ box (make sure it does not have DHCP capability to assign IP Addresses)
  7. Reboot your device and connect to WiFi
  8. Plug in Sonos one by one and let them come back
  9. Do not plugin the Boost
  10. Reinstall the Sonos app
  11. Open the app and select Join existing System
  12. Follow prompts and accept all options
  13. Sign in with your credentials
  14. Test your Sonos
  15. If all good proceed to setup the Brenan as a library connected to your router via Ethernet

Many thanks for responding in detail, AjTrek1.

I have tried many, many fixes over the years but will give this a go. The only point I didn’t understand was how I can make sure the FRITZ!Box does not have DHCP capability to assign IP addresses.

Thanks again.

What makes you say that? That only applies if the FRITZ!Box isn't also acting as a modem; that is, if another router is connected upstream. Manual IP assignment is not necessary.
