Subject: [Shtoom] unable to get the sound to work (win32, python2.4)
Message-ID: <766.678-10712-29916176-1158340006@seznam.cz>

# Hello,
# 
# i spent few days playing with the shtoom, but i always ended with some problems
# with audio. I ended up installing MSVC2003, .NET1.1, .NET1.1SDK, MSPSDK to
# compile the fastaudio module. I moved a little bit further but i am still stuck.
# This is the log the shreadder.py ends with:
# 
# [-] Log opened.
# [-] C:\Python24\lib\site-packages\shtoom\audio\interfaces.py:5:
# twisted.python.components.ComponentsDeprecationWarning:

# zope.interface.Interface instead. (also note that you should not use 'self' as
# the first arg on function decls in z.i.Interfaces).

# It looks like the dev close somehow does not work. skipping the assert line
# results in crash of python24. i tried to compile the module with latest
# libsndfile even the one recommended on the original pages and nothing works. any
# suggestions here? possibly the module of fastsound that is actually working with
# .24? i saw some cocoaaudio based thing in the svn repo, should i go that way?
# there's something about the environment vars in win32 that will choose the
# device... maybe wrong device is used in win32.
