Going from the information on that site, I would say that it probably won't address your question with the sound, no. However, I would suggest installing the patch(es) anyway--they really can help.
I don't know anything about the new collections (or Police Quest games in general), but see if you can find a file called "install.exe"--not setup. On the old DOS games, all you had to do was run that again to change sound settings after installing the game.
Please note I have no idea whether or not that will work for you--as I already mentioned, I don't have any of the new collections so I don't know how they are installed/setup, etc. Just throwing an idea out there.
