Have you tried sharing a clear close-up photo of the damaged component and the surrounding PCB? Someone familiar with Sonos Play:1 repairs might be able to identify it. The board location and any markings could also help. Hope you get it fixed!

Hello.. 

found the answer with Google AI. Someone in the community did post the component part no before. 


In a Sonos Play:1 logic board, U505 is an 8-legged surface-mount power management integrated circuit identified as a TPS54331 step-down (buck) voltage regulator.
