[Openal] no context open on non-dev computers

[Tim Mahrt]

Vrej,
I believe that:

devices=alcGetString(NULL, ALC_DEVICE_SPECIFIER)
device=alcOpenDevice(devices);

is the same as:

device=alcOpenDevice(NULL);

(unless there is some subtle difference I'm missing?)
I use the latter one and that opens the default device.
