[pygame] reserving an audio channel?

[Jack Nutting <jnutting@xxxxxxxxx>]

Hi gang,

Most of the sounds I've used in my games so far are short,
fire'n'forget thingies.  I manually grab a channel (so I can do
stereo effects) with pygame.mixer.find_channel(True) so that if there
are no available channels, it will grab the longest-running busy one.

Now I've got a sound effect that I want to continue looping under
certain conditions.  Unfortunately, since this quickly ends up
being the longest-running busy channel, it always ends up getting
appropriated by another sound.

What I'd like to do is essentially "lock" this one channel where I'm
playing the long-running sample.  I see
pygame.mixer.set_reserved(), but that just takes a number of channels
to reserve;  How do I specify that I want to lock just *this*
channel?  Do I need to first grab my channel and then call
set_reserved(1) before any other sound stuff?  That seems sort of
convoluted...  Also, the documentation says that "calling
Sound.play() will not use the reserved channels."  Does that apply
to find_channel() as well?

TIA,
