Hi,,, my cable is frayed very close to the exit from the sonos,,, and I was afraid to try fooling around with it until I read this post, because I didn’t realize that somehow, you could somehow pull out the cable to replace it, as it didn’t seem from originally looking at that area, that it was pullable, and also replaceable. Can you please confirm that it is pullable and replaceable, as that would be great. I have the Play 5 2nd Gen.with original cable,, and I think I would also try and get the longer cable when I decide to order. Thanks for any replies to my questions.
