Hi All,

I have a bit of issue with the Sonos setup.

I have an Opnsense router and unifi controller running on it for Wifi.

I have installed 3 One SL , 1 Sub 3gen and a Beam Gen2 
Only the Beam Gen2 is wired to an unifi switch this switch is set to RSTP.

The Sonos is connected to my home network where I have firewall rule all to all allow

I have 2 rooms, kitchen where 1 One SL is located
And TV corner where 2 One SL , 1 Sub and 1 Beam is located

Now the SUB does not play when added to the tv corner, only when I move it to kitchen is does work.

Now I adjusted the following:

• Auto-optimize network: off 
• IGMP Snooping: on
• Multicast Enhancement (IGMPv3): on
• Block LAN to WLAN multicast and broadcast data (Classic UI): off
• The Port where the Beam is connected to is set to Enable Spannin tree protocol
  
  
  But only wifi is also not working.
  I have turned the wifi off for the beam btw on wired.
  
   

Can somebody help me?
Is there an limitation?
