Missing Sound in Video Game... QuickTime Can't open "AIFC" Files

Recently bought "Alida," whose sound files are in AIFC format. Understand this is a common Mac sound file format, but for some reason no sounds show up in the game, and if I open QuickTime player and double-click any of the ".aifc" sound files stored in the game folder, QT returns the error message "The movie could not be opened." Clicking "OK" sends me another message stating that QuickTime needs another component to play the movie. Clicking "OK" there sends me to this page:
http://www.apple.com/quicktime/resources/components.html?os=OSX&ctype=73646563&c subtype=696d6134

Unfortunately, on that page are 11 different codecs, none of which address ".aifc" files. I've looked up the AIFC file format information on Google, and there is a lot, but no pointers to the correct codec for a Mac. Can anyone suggest what I need? My version of QuickTime is 7.6.4 (Pro).

Great links Bill, thanks.

I seem to recall in my research that there was more than one iteration of the IMA 4:1 codec, but was never sure what the diffs were. 😟

Found the problem... simple but maddening. Whenever I change the Display from its normal 1024 x 768 setting to 640 x 480 to play "Alida," my volume slider in the "Sound" file in "System Preferences" moves from its previous position to fully left, i.e. off. Also, whenever I open an Alida game, its sound option is at OFF, even if I previously set it to ON. Between those two bugs, one in my system and one in Alida, there was never any ambient sound and never any music. Now I know that I have to address sound volume every time I switch display resolutions and every time I open "Alida."

Computers are not here to stay!

Wow, that's a strange one, thanks for the report!

Can you try another sound destination like Earphones or such?

No earphones... also this problem existed both before and after a full Mac OS X re-installation.
