Cygwin (unix library on windows) sound broken. #217

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Under cygwin graphics works but sound is broken. I can play sounds under
cygwin with:
korg@cam korg/Desktop $ esdplay intro.wav

I didnt have all the cygwin libraries installed when i did the dumps below
so i went and installed everything under the audio group, but still the
same error.

Im not sure how much you'd care about this (given you can just use the
windows version of python) but it works out of the box with gl only stuff
(multiwindow, etc) it is just the sound that is broken so it's sooooooooo
cloooose.

Sorry to just handball, but my ctypes-foo is weak and my windows foo is
even weaker.

What steps will reproduce the problem?
1. Install cygwin tools (gcc, python, shell, audio packages, gl packages etc)
2. grab pyglet source code & extract & install
3. cd examples/noisy
4. /usr/bin/python noisy.py

Paste in the traceback or error message:

Any additional info (platform/language/hardware) that may be relevant?

This is the build/install process.... (I unaliased python from the windows
version so it would pick up the cygwin one).

**WORKED!!**

silent also worked (but without sound obviously!)

So it is just the directsound use which is broken.

GoogleCodeExporter commented 9 years ago 
DirectSound can never work under the cygwin build, as the cygwin build of ctypes
doesn't include COM support (the calling convention is different enough from C 
that
it can't be emulated from Python alone).

I've made pyglet.com fail on import if sys.platform != 'win32' in r1623.  This 
should
cause the DirectSound driver to fail on import at the appropriate time, so the 
OpenAL
driver should be used as a fallback automatically, without any environment vars.

Let me know if that works for you.

svn checkout and reinstall fixed it. Go pyglet, go pyglet... :)
