So while we wait for a OpenAL-Soft backend for Mac to fix the lack of EFX support, is there any way of using ASA (Apple Spatial Audio Extension) to add some filters and effects on my Mac?

The following returns true on my machine. Does that mean I can somehow access the extension through LWJGL? If not, how could it be done?
ALC10.alcIsExtensionPresent(null, "ALC_EXT_ASA");
