Re: [pygame] Mixer Quit / Restart

["Wyatt Olson" <wyatt.olson@xxxxxxxxx>]

This is correct; this is just an example showing the problem.  In my real program (a drum
sequencer), I load a number of samples which correlate to various elements in a drum set,
then play a bunch of stuff.  At some point in the future, the user can
switch to a different set.  When they do this, I unload all sound
objects, unload the mixer, and reload everything.  I unload the samples to save memory; there are potentially hundreds of MB of samples for a single set, and I don't want to leak memory if the user repeatedly switches back and forth.



As for setting the volume on the channel instead of the sound object, I
need to be able to play the same sample multiple times with different
volumes.  For instance, think of playing a cymbal - if you hit the
cymbal two times in quick succession, the first at volume 1.0, the
second at 0.5, you would want to hear the samples playing at different
volumes.  If you set the volume on the sound object, when you play the
second sample, the first sample's volume is reduced as well.



Everything in my main program is working, but just the unloading / loading code fails.


If you want to see a copy of the real program, let me know, but it is
much more complicated than this simple test case.  I just included the
elements here which demonstrate the problem.


Cheers

If I understood the original poster correctly, he was only presenting
that code as a test case. I believe his real intention would be to
re-init sound according to user-specified settings within an "Options"
menu inside a game.
