I get this error when I try to create an AL context. I'm not sure If it's a problem with my system (I'm running Arch linux and I would be surprised if I messed something up). It ends up calling the snd_pcm_hw_params_get_periods() function passing a NULL pointer
File: OpenALAudio.java
28 device = ALDevice.create(); // seems to return a pointer when I look at device.address()
29 ALContext.create(device);
connect(2) call to /dev/shm/jack-1000/default/jack_0 failed (err=No such file or directory)

I've found this issue which dates to a few days before the stable release
https://github.com/kcat/openal-soft/issues/26
I'll try a different release
EDIT: I switched to the nightly release and it's working now.
Please, update on LWJGL tree (git). So that way, openal library can be up-to-date with this issue.
