SONOS Integration Issue after Core 2021.9.7

Hi team,
I have an issue with my legacy SONOS devices no longer being available after I upgrade from Core2021.9.7
My legacy devices are Play5 Series 1, Connect AMP and Zone Player (these devices only workwithin Sonos’ S1 environment).
What I’m seeing is these devices become ‘unavailable’. All other current (S2 compatible) components work no problem when i upgrade beyond .9.7…
Can capture logs while it’s broken, but I prefer to have it in a working state.

My environment:
O/S: 4.19.0-17-amd64
Version: core-2021.9.7 (stable) anything after this fails with old SONOS (S1 compatible only) devices.
Docker: true
O/S family: Linux

Anyone else seeing same issue?
