Vero 4k+ & Sonos Arc interference

Hi Sam, i realise it is Febuary but i hope you had a good festive period.
I’ve been checking in on this issue and see nthis post 4k+ CEC EARC issue - #58 by darwindesign that suggests the issue does lie with CEC and siabling it at the physical layer is the solution. While this will i imagine “fix” the issue i don’t see it as a solution. What’s your take on it? Is there anything i can do to assist with diagnosing? Would you say the pin 13 disabling is a legit method (assuming you don’t actually want to use CEC functionality on the Vero).
