wireless clients not receiving multicast traffic

I have a Cisco 3504 WLC with 2802 APs. My switch is an Aruba 2930

Wired devices connected to the switch are getting multicast traffic As soon as I change the device from wired to wireless, it stops receiving multicast traffic.

"Enable Multicast Mode" and "IGMP Snooping" is enabled on the WLC

The multicast sender is attached to VLAN 200 on my Aruba switch The wireless client is associated to an SSID that is tagged to VLAN200

Any ideas what could be causing this?

It seems I am missing a setting that allows multicast traffic on the switch vlan to be forwarded to the 'air'

Thanks
