King's Quest III: To Heir Is Human's original requirements:

Problem - Music only comes over PC Speaker:
You get the one MIDI voice beeping through the case speaker. This is not a bug, this is the way the games were made. They did this when these games were new.
Play the game in DOSBox. If you change dosbox.conf to set "machine=tandy" instead of "machine=vga" there will be 3 voice PCjr/Tandy music with a white noise channel. You can also get Tandy sound in Sierra's AGI games without having to emulate Tandy video mode if you run "sierra.com" with a "-t" after it in the game's directory, i.e.:
Use a patch by Anders Olsson, agi-mid05.zip (12 kb). You will hear all three MIDI voices through your sound card. (2K and XP users will also have to run the games with VDMSound to hear it.)
Solution 3 (preferred):
Run the games with one of the new third party AGI interpreters such as NAGI or Sarien. With NAGI you'll hear all three MIDI voices and even have limited mouse support within your AGI games.
Solution #1 (preferred):
Run the game with DOSBox. You can hear all three MIDI voices if you select "machine=tandy" in the dosbox.conf.
Run the games with one of the new third party AGI interpreters such as ScummVM, NAGI or Sarien. With these three interpreters you'll hear all three MIDI voices and even have limited mouse support within your AGI games.
Note: DOSBox and NAGI have the best sound emulation of all these solutions.
There is a specific problem with the collection version of the game.
There are mistakes with the manual from the collection for King's Quest III. See the Spell Corrections page for help.
