Hi @Awp23 

If you have enabled the recommended configuration for unleashed to work with Sonos, there are no other necessary changes to make on our end, however I will recommend you contact Sonos support, who can pull the logs, to make sure if there are any issues related to multicast, the ICX7150 switch will simply pass the traffic coming from the access points to your ISP router.

Best regards,
