HyperCard: Unable to Capture Sound on PCI-Based Systems (2/96)

I am trying to input audio into a HyperCard stack on my Power Macintosh 7500 computer. The sound seems to record fine, but when I play the sound back, all I hear is crackly, static noise. I have tried both HyperCard Player and a full version of HyperCard 2.3.3 and different microphones and computers.
Apple Engineering has recreated this issue on Power Macintosh 7200, 7500 and 8500 computers. This problem may also occur on Power Macintosh 9500 computers. This issue is fixed in the HyperCard 2.3.5 Stacks update posted online.


These articles can help you locate the HyperCard stacks mentioned here:

* "Where To Find Apple Software Updates" - Lists online services for free Apple software updates.

* "Obtaining Apple Product Support in the USA" - Lists 800 numbers and online services for software updates, Apple support information, and a subset of the Apple Tech Info Library.


Article Change History:
07 Feb 1996 - Added online fix availability.
25 Jan 1996 - Clarified methods.
11 Jan 1996 - Added additional sound import workaround options.
