[Openal] Clipping with looped samples

[Marius Zirngibl]

Hello,

I'm trying to implement a continuous sound with OpenAL. The idea was  
to load a sample in a buffer, play it back with the source set to  
LOOPING and then change the pitch of the source when necessary.

It basically works, but when I change the pitch too much, you hear  
some clipping in the sound when the source is "rewinded". When I leave  
the pitch at the original value, the output is perfect.

Is this a "feature" of OpenAL? Or is there any way to get around this?

Any help would be appreciated..
