But it used to work with Xcode 1.5 and the same hosts. But maybe
it's a changed policy in the versions of the OS and/or development
tools then. That's OK (but I don't think that's the problem).

Yes, but it's almost the same with AU Lab. AU lab does start though,
but it refuses to load any AUs, not even Apple's or any other
manufacturer's.

That's why I haven't, because I don't think this is a host problem.
I use the latest CoreAudio SDK 1.4.3, but it looks like it's some
library compatibility issue. Maybe some frameworks. When AU lab is
started from Xcode 2.0 / GDB, then none of the AudioUnits are loaded.
However, they are when it's started without a debugger. They all
echo the following (snippet):
code 4, error number 0 (Symbol not found: __FSOpenForkWithCatalogInfo

Looks like there are some new frameworks which need to be included in the
project to enable debugging. I'll check the sample projects in the CoreAudio 1.4.3
SDK, if sample projects were included. But ff anyone has a clue...
