[Openal] no context open on non-dev computers

[Tim Mahrt]

Hi,
I've developed a little test program for demonstrating OpenAL,
however, it seems that it only works on my computer.  When I run it on
someone elses, alcOpenDevice(NULL), fails to return a device.  This
has been tried on three different computers that I do not develop on.
I did get my project compiling on one of them though, however, it was
unable to open a device.

Are there some pre-requisites required to get an OpenAL context?  Does
the user have to install anything?  I tried to make my project
stand-alone since its just a simple demo.

If it helps, the file can be downloaded here:

Just run the exe file.  Pressing "z" on your keyboard will continually
loop a laser sound.  Pressing "x" will play it once.  The sound is
"tied" to the moving box.  The listener is at (0, 0, 0) although the
camera is not.

Thanks,
Tim
