Some of my Sonos speakers don’t show volume sliders in the app and it’s driving me crazy. Audio plays fine and grouping works, but I can’t control volume for some of my speakers. It always ends up that one volume slider remains, while the rest disappear. And this on al my devices, they even show the same volume sliders grayed out.
What I’ve already tried:
-
All speakers are on the same 5GHz network, same AP
-
Disabled AP isolation, client isolation - no change
-
Turned off WiFi band steering - no change
-
Played with IGMP snooping settings on my switches - still broken
-
No multicast rate limiting configured
-
Speakers have static IPs assigned
Wireshark shows that all speakers are communicating, on both IGMP and SSDP. Even the ones that don’t show the volume sliders. The only thing that works is restarting my router, but even then the problem always returns. Running TP-Link Omada AP, Router and Switches.
Anything else that i could try to resolve this issue? Talked to support on the phone aswell but, they couldn’t help me unfortunatly
