Re: 1.2alpha1 audio issues

What format of sound file are you using?

Hey, new to pyglet but I've been using it for a game on a newish Mac OS X.

While audio works, it frequently stutters and freezes the ENTIRE APPLICATION graphically if I play too many sounds at once (even with a forced 4-channel setup, where I don't let my app play more than 4 sounds at once).  The application continues after all of the audio files have finished playing, but it seems to have "continued" underneath - that is, when it freezes, multiple updates happen, rather than just one update with an absurdly large delta.  

It's pretty disruptive and pretty sad to only play 4 sounds at a time and still have some major performance issues... seems like a bug.  Anyone seen anything like this?  And I'm loading my sounds like: 

pyglet.media.load(soundFile, streaming = False)

So it would seem to not be the streaming vs StaticSource thing.

Any suggestions would be awesome, Thanks!

AIF.  I found the problem though.  The openal driver isn't properly releasing all buffers for whatever reason, which means that it's just running out of buffers.

See attached patch.

Oh, there was also a thread starvation issue.  That's why I had to add a sleep as well.

Richard or another commiter, please take note of Walter's patch!

Walter, did you create an issue on the google project tracker for this?  It's less likely to fall through the cracks if you do.

The patch wasn't against pyglet trunk so I had to manually apply the changes.

Walter (and other interested parties) please try out the changes to
make sure it's all as intended!
