IGMP snooping and COMPLETELY wired Sonos set up

I have seen so much conflicting info on this.

If ALL of my Sonos speakers are hardwired into the LAN, and Wifi is turned off in the Sonos controller for all speakers, is IGMP snooping or STP necessary at all? Or does it take resources from the switches/router that is not necessary?

Thanks in advance.

The recommendation is that IGMP snooping is enabled, to reduce the overall network load. 

 

Despite being wired with radio disabled, such Sonos units still have STP enabled. As a wired/wireless loop can’t form, they might not care if BPDUs are blocked in the switch. You could however end up with multiple root bridges. You can always try it and see.

By the way, you’d have to wire the Sonos devices first, in order to disable their radios. If the switch blocks BPDUs you could find the network collapses before you’re able to do so. In that case you’d have to sort out an alternative interim topology.
