In the process of trying to get the Amiga Version of Myst to run on my G5 I seem to have mucked up my AHI settings.

I now have no sound within Ambient, although running videos on Wayfarer still provides audio.

I believe this is because I ran the old AHI prefs app from the Myst CD-Rom at one point and this has changed my underlying settings. I did manage to change it back but I must have clicked used rather than save as its not working again now and now the AHI prefs app is refusing to option for me.

Is there a particular file I just need to delete to get rid of my audio settings so I can start again?

Don't worry I found it!

Deleted AHI.prefs in EnvArc and it seems to have fixed the issue.

Remember that you should also find old versions of the file from the .recycled directory in this kind of situations, for example from System:.recycled/ (assuming you have SFS).
