It all works fine except i'm unable to group more than 2 speakers together, pairs work fine but any more and only one speaker plays.
I've read that this can be caused by WIFI latency however not sure this is the case here, each speaker has a static IP (using DHCP reservations) and the ping time to each one is sub 1ms
Any help appreciated!

The datasheet shows the switch as having a few different multicast settings, can you disable IGMP snooping if it's currently enabled?
You mentioned that only one speaker will play when grouping three or more together. Is the speaker that continues to the play the group coordinator (the speaker all others were grouped to)?
Can you also break down the network topology for me a little more (include the make and model of each device)? Are there any hardware firewalls or are there any firewall settings enabled on the switch?
