Hi klappnase,


I'm not too familiar with the tkSnack module, and I'm not sure if any of
us here can help diagnose the problem; it sounds more like an operating
systems issue more than anything else.  you may want to contact Snack's
author, according to:

    http://www.speech.kth.se/snack/FAQ.html



We can, at least, see Python syntax errors... *grin* Are you sure that's
not missing a quote sign here?

         fileformat="WAV", byteorder="littleEndian,\
                                     ^^^^^^^^^^^^^^^



[off-topic, sorta:

    If you are running on a Linux system, you may want to double check
    that your hard drive is tuned to performance:

    Most Linux systems are very conservative in the way they use their
    hard drives --- you may be running into a simple IO issue.

Good luck!
