The weird thing is that this was totally working great before modular 
Xorg.  I'm really thinking it's just a matter of reinstalling 
something.  I just don't know what.  Also, when I play the .wav file, it 
plays for like a split second, and then mplayer just hangs.  But I do 
hear it for that first short second.

Here's the output from doing that:

It does the same, plays for a short second and then it still locks up.  
I have an mp3 that runs at that rate and it works fine.

Thanks a lot for your help and patience so far, btw.  I really 
appreciate it.
