LWJGL2 is pretty much unsupported at this point due to it be so old and probably broken in many ways, so would definitely recommend you move up to LWJGL3.Having said that there is an OpenAL tutorial series (7 parts) for LWJGL2 on the old LWJGL 2 wiki found at wiki.lwjgl.org , however it appears the wiki is down but can be viewed using the Wayback Machine.
