Having some trouble with the play_pan method in Windows, and I suspect I'm doing something wrong.
A pan value range of -1 to 0 gives increases volume in the left channel, with zero sound in the right. When it crosses the 0 threshold, there's an abrupt change to full volume in right channel only.
The pan values appear to be correct. (floats in the range -1.0 to 1.0). This is the behavior with mono wav files. Trying to pan a stereo wav has no noticeable effect (full volume in both channels).
Any idea what's going on here?
