We can use no Alure Class to load a .wav file into an audio buffer.
We can load directly the "row" audio data of a wav file in 3th parameter of Al.BufferData() method.

 Okay Benoît, you can take me off
 your list of people to kill now that 
 I've finally gotten around to implementing OpenAL. :)
 
 The documentation online is pretty spartan, with much of it
 being 
 outdated, but I still managed to set things up reasonably
 well to play a 
 sine wave at a specified frequency and I think I've found
 the function 
 to load a .wav file into an audio buffer in order to play
 it. The latter 
 doesn't work, however. The "alure" class seems to be similar
 to "glu" in 
 that it's a high-level "helper" class to make common
 functions easy, 
 such as loading sound files directly.
 
 This line should load the .wav file into the buffer and
 allow me to play 
 it, but it returns False:
 
 Print Alure.BufferDataFromFile("./test.wav",
 AudioBuffer[0])
 
 Here's the example project if anyone wants to play with it:
 
 http://eightvirtues.com/misc/OpenAL_Example.tar.gz
 
 This issue is probably unrelated, but on running the program
 this 
 message displays in the debug window:
 
 "Error loading libdumb.so.1: libdumb.so.1: cannot open
 shared object 
 file: No such file or directory"
 
 libdumb is described as "DUMB is a tracker library with
 support for IT, 
 XM, S3M and MOD files." so I don't think that's an issue
 here. If OpenAL 
 support it however, the library might need to be added as a
 dependency 
 during compilation.
