Hi @Richard Seery
Thanks for reaching out.
I appreciate your detailed post outlining your concern, I’d be glad to help.
Sonos usually refrains from recommending 3rd party products, it’s best if you can check the Sonos system requirements and the list of networking equipment that has been tested and confirmed as incompatible with Sonos.
Sonos allows you to stream your music library from any computer, or network-attached storage drive (NAS), to your Sonos system. This article will show you how to add your music library using the Sonos app for macOS or Windows. To use a NAS drive with Sonos, the NAS must support the SMB(v1)/CIFS file-sharing protocol.
Hopefully, that helps, and if you have any other questions or concerns, please do not hesitate to reach out, we’re always here to help.
