Hey Peter,
I couldn't find the files in your Dropbox folder, but I do believe you.
It depends what version of SL you are running. The bug was introduced somewhere around 10.6.5 IIRC.
I forget the version numbers, but the final version of SL (10.6.8 I think) had the bug, so the volume would be the same as later versions.

If you were to do a comparison between Leopard and Snow Leopard you would hear the difference.

I do a lot of background music for a friend's video business, so I re-use a lot of old work as starting points, and then build on them.

The change in volume messed up a lot of my earlier work, and rather than change all my earlier stuff I just went back to my external sound module.

My thinking was when Apple fixed the bug, I would have to go back and change everything back again, so I never bothered.
