I'm a long-standing user of pyglet, and today I was installing it on a
new machine running Windows7. For a while I was getting an error
importing pyglet.media:
import pyglet.media
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "C:\Python26\lib\site-packages\pyglet\media\__init__.py", line
1340, in <module>
driver.driver_init()
File "C:\Python26\lib\site-packages\pyglet\media\drivers\directsound
\__init__.py", line 378, in driver_init
lib.DirectSoundCreate(None, ctypes.byref(dsound), None)
File "_ctypes/callproc.c", line 925, in GetResult
WindowsError: [Error -2005401480] Windows Error 0x88780078
Turned out that this was because my new system was detecting that I
had no speakers/headphones connected. :-/ As soon as I connected them
it worked fine (and removing them reverted to the error message). I'd
say pyglet should handle lack of speakers with a warning or some such.
Apologies if this is a known issue - I couldn't find any mention of it
with google (am I really the only person not to connect speakers to a
PC for a period?!)
My system info below, with headphones connected.
cheers,
Jon
