Hi.

How are the sound files loaded into memory? The only things I can think of to 
cause the noise is either if:

It's part of the sound; either by junk at the end, or the waveform not ending 
"cleanly", or..
It's being loaded incorrectly; sometimes .wav files will have extra chunks 
after the sample data, so if care isn't taken to not read beyond the data 
chunk, you can inadvertently read this errant data, or..
The specified size being given to alBufferData is too large; make sure the 
size given is the size of the data chunk.

If you can, it may help if you can provide source for a small program that 
shows the problem (along with the offending .wav files).
