OpenAL-Soft invalid enum error AL_FORMAT_STEREO_FLOAT32

I'm trying to play wav file that has a 32bit bit per sample format. When I try and generate an OpenAL databuffer and give it AL_FORMAT_STEREO_FLOAT32 as a parameter for the format type, I get an OpenAL error code 40962 which I believe means invalid enum.

Why is that happening?

Here is how I generate the buffer in OpenAL.

alBufferData(buffer, AL_FORMAT_STEREO_FLOAT32, fWavDataIn, wavHeader.subChunk2Size, wavHeader.sampleRate);

8 and 16 bits per sample works just fine with AL_FORMAT_STEREO16 and AL_FORMAT_STEREO8. But AL_FORMAT_STEREO_FLOAT32 doesn't work. Why?

AL_FORMAT_STEREO_FLOAT32 is not a native feature of OpenAL. You should check for "AL EXT Float32" in the alGetString( AL_EXTENSIONS ) before using floats.
