[Openal] Generic Software: no errors but no sound

Hi,

I've got this problem for a very long time and can't find a solution :

I am using OpenAL, with Visual Studio 2008 on Windows, * without ALUT *, 
and when I use the "Generic Hardware" device, everything works well : 
wav samples, ogg streaming, 3D sound, Doppler effect, multiple channels, 
multiple sounds... No problem. But with the "Generic Software" device, I 
ear a /click /when the program begins, the same /click /when it exits, 
but no sound and no error (I check EVERY OpenAL call). Generic Software 
is important, because several computers don't have a hardware device 
available.

- Same thing on a PC with no hardware device (no sound at all since 
"Generic Hardware" is not available);
- Reproduced on both Vista 64bits and Xp SP2 32bits

I'm building OpenAL from the SVN repository (creating wrap_oal.dll and 
openal32.dll, and linking my project to openal32.lib).
I've tried the openAL 1.1 SDK from Creative (headers, lib and 
installer), and I get EXACTLY the same problem: no sound with "Generic 
Software", on both PCs.

I don't understand the problem, but I can play sound from old openAL 
samples (using ALUT), even on the PC with no hardware device, it works.

Google has not helped me (I've found a few guys having the same issue 
but I didn't get any solution);


Please, any idea ? I spent several nights on this and it is really 
getting on my nerves :/


PS: Actually I ear a very very very low continuous sound, I've tried to 
amplify it (using OpenAL Gain then with Audacity) but it's weird. I've 
uploaded it here (very very amplified):
