Okay, the different classes explain the different behavoirs then because
zretune crashes instantly:

(gdb) r --cent 20 test-orig.wav out.wav



Starting program: /usr/bin/zretune --cent 20 test-orig.wav out.wav



warning: Could not load shared library symbols for linux-vdso.so.1.



Do you need "set solib-search-path" or "set sysroot"?

Ya, nevermind it, that's always printed but gdb does its job for
backtraces :)

I saw the ALSA-errors, too but can't test it right now since I currently
only have the library-part of zita-alsa-pcmi installed. Will install the
other binaries tomorrow and test it then. I can do tests on a pure
32-bit machine if it helps.

Thanks for the help up to now :)
