Set the source's AL_AUXILIARY_SEND_FILTER_GAIN_AUTO property to false. That 
disables any reverb-based distance attenuation for the source. The source's 
AL_ROOM_ROLLOFF_FACTOR can still apply distance attenuation on the room path, 
but that is 0 by default which effectively disables any distance attenuation.
