I don't know about HP-switches or whether they do support IGMP-snooping out of the box already,
Almost all HP switches supports IGMP snooping, but none as I know by default, i.e. it has to enabled per VLAN.

What is the querier?
One node in the network could be the querier who collects IGMP group memberships for the LAN, which could be used for advanced multicast routing.
However, that is not needed for getting switches to learn IGMP-to-switchport.
Just enable IGMP on each switch and for the specific VLAN.
