Hi @ahdoor
Welcome back to the Sonos Community!
The issue that allowed Play:1s to be bonded to an Arc Ultra was resolved soon after Arc Ultra’s release. As I understand it, anyone who managed to bond their Play:1s to an Arc Ultra will still have them bonded, but no-one else will be able to do so, and anyone who did and un-bonds them will not be able to re-bond them. In addition, TruePlay Tuning will not be available (again, as far as I understand it) to Arc Ultra systems with Play:1s bonded as surrounds.
So, the short answer is: no.
I hope this helps.
