Apologies for resurrecting an old thread, but turns out enabling IGMP snooping on the bridge was key to getting AirPlay to work across VLANs!
Without it, streaming to a HomePod would start for a second and then stop. Streaming to Sonos speakers worked fine. Apple devices apparently use multicast, Sonos does not.
AirPlay across VLANs with different subnets works, you need an mDNS repeater (the mDNS repeater docker image from https://hub.docker.com/r/scyto/multicast-relay works a treat, and as a bonus also repeats the SSDP protocol that Sonos uses besides mDNS) and as it turns out you need to enable IGMP snooping on your bridge.
The firewall rules between the VLANs to get it all working are left as an exercise for the reader, I'm still working on locking those down. You can always just allow AirPlay device unfettered access to the VLAN with clients.
