I appreciate any assistance provided.
Hi. I don't know the exact nature of the problem, but there just might be a way around the issue altogether. The GOG installation includes the original CD mirror you can burn to a disc, which you can than install using a custom installer from zetafleet for modern systems. I found this alternative installation method in the following thread, post 23 and 25 by Gremmi: https://secure.gog.com/forum/gabriel_knight_series/bad_sound_quality/page2
Here's the highlights:
One last thing to try if you're desperate to play the game (though this is a bit of a lengthy process):
Browse to the installed folder
Find the file GK1.gog.
Open this in WinRAR and extract all the files to a directory (say C:\GK1)
Download and run the GK1XP installer from http://gkpatches.vogons.zetafleet.com
Point the installer to the GK1 directory.
This will then install the Windows version for you, which should avoid any DOSBox sound conflicts.
and post 25:
Ah, I just tried it myself and the GK1XP installer's been updated since last time I used it so it only works off a CD. You'll have to burn the extracted files to a CD, then run the installer.
I used this method myself to solve an issue different from yours (this installation doesn't use DOSbox), and others have used it to solve yet another problem (the sound issues Gremmi originally adressed in that thread) maybe it works for you too. It's worth the effort, if only for the alternative intro music. I really hope this works for you.
