[python-win32] Python sound playback threading control?

[Jacob Kruger]

Well, it's currently making use of the sound_lib module - not sure which API 
it's using as such - but am using the stream object's play_blocking() 
method, which seems to be meant to interrupt other playbacks, but also 
played around with first using the stream's stop() method, before then 
trying to initiate .play(), or play_blocking(), and while they all seemed to 
work a little differently, none of those options seemed to really handle it 
quite like I would have hoped for/expected, in terms of just cutting sound 
playback off immediately, and then initiating a new playback, or something - 
suppose should also test this a bit on another machine to make sure it's not 
the machine am currently working with a form of performance lag, or 
something.

Alternatively, any thoughts on something simple could try using that would 
offer something similar in terms of just, at least being able to manipulate 
playback pitch, at least 2D panning, pausing/stopping on demand, etc.?

And, got hold of that sound_lib module from here:
