KEF LS50 Wireless set up challenges

I bought a Sonos Port so I could play music though my KEF LS50s and Sonos Arc simultaneously. I was told before purchase that hardwiring the KEFS via RCA wires would work, but after spending 1.5 hours on the phone with tech support we couldn’t connect the KEFs to the Sonos App. We set the KEFS to auxillary, plus I tried all other settings afterwards, with no success. The Port is refurbished and I am wondering if that is the problem. The tech said that I needed to buy an optical converter since optical worked before with a Sonos Connect. A good converter costs more than 150.00 and I really want to see if I can avoid spending money on yet another purchase. What am I missing? What am I doing wrong? All advice welcome. Thanks!!!!

Hi, My KEF speakers don’t appear to have a digital audio in slot. The subwoofer slot looks like it takes a digital audio connector, but I doubt that would work. Here is a photo of what is available. RCA has not been successful. Any other ideas? Thanks.

RCA to the AUX (C) inputs should work, unless the Port is faulty.

To use the Port’s digital out you’ll need a coax-to-optical converter (plus an optical cable). I don’t know your country but they cost £15 or less in the UK. You’d then connect to the Optical (B) socket.

The Subwoofer (S) socket is an output.

    That Sub-woofer (S) plug looks to be a mono- RCA

    My KEF LS50s are now working with my Sonos system using the RCA plugs. The issue was sadly user error. It turned out that the Sonos Port required the volume on the KEFS to be turned up significantly higher than the previous Sonos Connect plus the volume button on the KEFs is no longer responding as it did. It flashes as if volume is maxed out, though it is not. I do have one lingering question. I was not able to install the longstanding driver update on the KEFs LS50s. The update failed and I couldn’t successfully reinstall the system software working with KEF support for nearly two hours. I am wondering if I am sacrificing sound quality running on the old drivers or if I should just leave well enough alone now that I have a functional system. Thanks for your advice.

      The driver question might best be directed to a KEF forum.

      Good to hear you have them working for you.
