It is true that "Addresses with Audio" and "Appointments with Audio" don't work with the AV Macs. However, the Addresses and Appointments stacks that ship with HyperCard 2.2 do work with the Audio Recording capability in HyperCard.
The problem with the audio stacks is in hardware differences between the DSP chip in the AVs and the Apple Sound Chip in other machines. HyperCard 2.2 and the 2.1 audio stacks work OK with Sound Manager 3.0 on other machines that we have tested.
