HyperCard: Stacks w/ Audio Don‘t Work on AV Machines (5/94)

The stacks "Addresses With Audio," "Appointments With Audio," and "Audio Help" from HyperCard 2.1 do not work on the Macintosh AV machines.

From what I can tell, the "Audio Help" stack included with HyperCard 2.2 does work on the AV machines. I presume that this means the Addresses and Appointments stacks included with HyperCard 2.2 also have audio capability and work on the AV's, is this true?

Is the incompatibility with Sound Manager 3.0 in the ROMs on the AVs and not with the AVs themselves? If so, this issue could affect any CPU with Sound Manager 3.0.

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.
