[Openal] Check the input volume of imicrophone

[wassim_belhadj at topnet.tn]

Hello,
My application needs to record the sound of the microphone. But, I am
worrying the user may set the microphone input volume mute by accident.
So I want to use some codes to check it and set the volume of microphone
input maximum.
Can I do this test using OpenAL?
If yes, how  to do this?

Thank you in advance
Best regards,
