You mean the microphone gain/volume level? There isn't. It's not too difficult 
to apply a volume adjustment on your own during capture, though. For example, 
with 16-bit:

alcCaptureSamples(CaptureDevice, Buffer, NumSamples);
for(i = 0;i < NumSamples*Channels;i++)
    ((ALshort*)Buffer)[i] = ((ALshort*)Buffer)[i] * Gain;

where Gain is a multiplier value (1.0 is normal, 0.5 is half, 0.0 is silence).
