Sound Doesn't Play

[TheBitPriest]

Sigh.  Forgive me for posting what might be a really simple, oft-treated question...  I searched the forum, but I didn't see a solution. 

I'm still a little mystified by the sound system in AGS.  In my mind, this should always play a sound:

aSoundFX.Play(eAudioPriorityHigh);

But it doesn't.  What am I missing here?

Can you give a bit more information? Like - do other sounds able to play? Are there any other sounds playing at the same time, and what is their priorities (also, what is default priority for the sound folder(s) you have in project)?

maybe you added it as a soundfx and didn't define a fx channel? give more info pls.

I know that was a terrible description of the problem.  Please forgive...   

It seemed so random, but I think I've figured it out -- at least, I have this particular effect playing.  The effect that was I working with when I became frustrated enough to turn to the forum happened to be in stereo.  I changed it to mono, and now it works. 

Is there any reason why that would be? 

EDIT:  Some related questions:  I have read everything pertaining to sound in the manual.  Is there another source for information on the internals of the sound system in AGS?  When a sound mysteriously does not play, are there any recommended techniques for debugging the sound system?
