We have Aruba OS 18.104.22.168-airgroup installed on all of our controllers and are having trouble getting Airplay to work over vlans/subnets.
It wasn't until I enabled IPv6 on the master controller that started it to work, across vlans/subnets, flawlessly. I did read somewhere that it's not a good thing to leave IPv6 enabled.
Solved! Go to Solution.

I don't know where you would have read that it's not a good idea to leave ipv6 on? It could be a security recommendation for those not familiar with it, but I can't see why it would be an issue as long as your firewall rules were appropriately set for users? I suppose it might load the CPU more than necessary if you aren't using it? In fact, I actually had to enable it for a customer recently who uses IPv6 as the primary and preferred protocol (human genetic stuff).
The only reason in your case I can think that it started to work after enabling it, would be that the transmitting client was actually using IPv6? I've noticed some clients these days will use IPv6 in preference to IPv4 if they get issued and IPv6 address or have one configured. Is that possible in your case? Check the client settings, or sniff its transmit packets to check?

Nevermind. We needed to open up various ports on our ACLs between the VLANS as per Aruba's instruction...
The ArubaOS role-based access controls for wireless clients use ACLs to allow or deny user traffic on specific ports. Even though mDNS discovery uses the predefined port UDP 5353, application-specific traffic for services like AirPlay may use dynamically selected port numbers. Best practices are to add or modify ACLs to allow traffic on the ports described in Table 24 and Table 25.
AirPlay operates using dynamic ports, but printing protocols like AirPrint use fixed ports.

Ports for AirPlay Service
Enable the following ports for the AirPlay service.
