It depends on the device. With Sonos it's an issue due to it's mesh wifi network always being on and the Sonos system acting as a wireless bridge so you can extend a wired network with the Sonos zone players - a feature that I rely on, not ideally, for network access between my router and office but wish to do away with when I can be bothered to run that catx cable and replace my existing switches with ones that support stp.

For same reason, airport express can also suffer when configured in extend network mode and you accidentally get multiple wired and wireless routes.

I see you have squeezebox. Not sure if it is an issue with them. Certainly early versions did not have complex wifi capabilities such as bridged networks but think it may have been added in more recent versions as I recall some feature about connecting wired devices wirelessly through sb but this is not the same as a sonos mesh network where zone players talk to directly to each other via their own network and not via the wireless router.
