Do you need to do this while it plays over a real device? If so, there's the 
AL_EXT_FOLDBACK extension:

http://icculus.org/alextreg/wiki/AL_EXT_FOLDBACK

It allows you to define a region of memory that receives a mono or stereo mix 
of the processed audio data while its played over the device, and to be 
alerted when new chunks of audio data are ready.

Note that only the Rapture3D OpenAL driver currently implements it, AFAIK. 
OpenAL Soft doesn't support it right now, but it may in the future.
