What happens if you delete the OpenAL32.dll that comes with LWJGL and try again?
Then I'll get an LWJGLException
("Could not locate OpenAL library") and the resulting UnsatisfiedLinkError
But here's what may be a clue. This is the output produced by the constructor of org.lwjgl.test.openal.BasicTest
is run using the OK-sounding 2.8.3:
Default device: DirectSound Default
0: DirectSound Default
...whereas 2.8.4 prints this:
Default device: OpenAL Soft
0: OpenAL Soft
Edit: Or perhaps that's just a naming issue, and the real problem is elsewhere. The OpenAL Soft commit log for 1.14
contains a number of commits related to device names.
