Player set_pitch crashes with 'directaudio' driver

[GoogleCodeExporter]

It works perfect with openal driver, according to:

http://www.pyglet.org/doc/api/index.html

This is Pyglet 1.4 alpha1 running on Windows Vista Home Basic SP2, Python 
2.7.3. Using AVbin 11.

This was 1.2 alpha1, sorry :)

I also encountered this issue and could fix it.

Fix: 
* Open "Python27\lib\site-packages\pyglet\media\drivers\directsound\__init__.
py"
* Go to the "set_pitch" function around line 425
* Change this: frequency = int(pitch * self.audio_format.sample_rate)
* ..to this: frequency = int(pitch * self.source_group.audio_format.sample_rate)

The problem was that audio_format is not a direct member of "self" but belongs 
to self.source_group.

Greetings,
Hauke

Thanks again for the patch!

I didn't see what was the problem when I reported the issue and because I use 
OpenAL, I didn't investigate any further :)
