ok, another few questions then :P

What tool did you use to find out the format? Would make it more easy
for me to identify such things problems, since this isn't the first time
i ran into this trouble.
But what still is kinda weird then, why did it work with the old void
alutLoadWAVMemory then?

Anyway, I checked libsnd now deeper, and aside the fact that I have real
problems with all the digital audio stuff I'm not aware of, it more and
more seems a bit overkill for this purpose :(
I'll keep working on it, but hell...

Does anyone know another lib i could use instead of alut to make sure
that wav formats like the one above can be loaded with a simple
interface like alut?
Problem is, I can't control which formats were build in the different
maps or mods in the game I'm writing this for :(, so I have to take care
that as many different formats as possible are supported.
