Beosound Core + Beolink Converter NL/ML + Spotify Connect issue (MasterLink distribution) Hello everyone, I have a hybrid Bang & Olufsen setup combining older MasterLink products with newer Network Link products, and I am trying to understand whether I am facing a configuration issue or a technical limitation. My current setup:

• Beosound Core (older version, not the new 2024 version)
• Beolink Converter NL/ML Firmware version: 1.4.6.1
• Beovision Horizon (Network Link)
• Beovision 10-40 (MasterLink)
• Beosound 3500 (MasterLink)

The Beolink Converter is configured as:

• ML role: A Master
• Primary product: Beosound Core
• Secondary product: Beovision Horizon

Current observations: 1. B&O Radio via Core works perfectly I mapped B&O Radio from the Core to RADIO on MasterLink. Result:

• Radio plays perfectly on Beosound 3500
• Radio also works on BV10
• Stable playback, no interruptions

2. Bluetooth streaming works If I stream music from my phone to the Core using Bluetooth:

• The music is distributed correctly over the ML system
• Playback works on Beosound 3500 and other ML products

So NL to ML audio distribution is working. 3. Spotify Connect does NOT work When I start Spotify using Spotify Connect directly to the Core:

• Spotify starts correctly on the Core
• The Horizon can play the Spotify stream

But:

• The ML products immediately stop receiving audio
• If I select N.MUSIC (mapped to Core → Music) Spotify stops immediately
• No sound is distributed to MasterLink products

I also tested this while B&O Radio was already playing over ML. Scenario:

• Core playing B&O Radio
• ML system playing radio normally
• Start Spotify Connect to Core

Result:

• B&O Radio stops immediately
• Spotify does NOT continue on MasterLink
• ML audio disappears completely

Important: Bluetooth streaming DOES work. Spotify Connect DOES NOT work. This seems Spotify-specific. My question: Is this a known limitation of the older Beosound Core + Beolink Converter NL/ML combination? Or is there a specific BLC configuration that allows Spotify Connect to be distributed over MasterLink? At this point it seems that:

• B&O Radio = works
• Bluetooth = works
• Spotify Connect = immediately breaks NL → ML audio distribution

Any ideas would be greatly appreciated. Thank you.
