[Openal] Unable to open the device capture ???

[wassim_belhadj]

Dear list 

I'am using Openal to record  Sound.

I am using  a usb  Microphone to capture sound (PHILIPS SpeechMike)  

I have an error message indicating that the initialization of the capture
is impossible.

It is at the methode  "alcCaptureOpenDevice" ==> Unable to open the device
capture

It is noteworthy that the name of the device is passed as parameter  after
extraction devices contained in the returned string

of methode alcGetString.

Please help me and thanks in advance.
