alcOpenDevice sets the device's specifier string to whatever you passed to 
alcOpenDevice. When you pass NULL, it sets an empty string.

I think the device string handling can be reworked a bit to be more dynamic 
(remove the "Default" device string, and query the list of backends to build 
a list of device names, etc). I'll see what I can do about getting a patch 
for that, but it might conflict with some changes that are waiting to be 
applied.


In the mean time, you can call
alcGetString(NULL, ALC_DEFAULT_DEVICE_SPECIFIER);
to get the default device name, then pass that to alcOpenDevice (passing NULL 
should be the same as passing the default), which should create the device 
using its name.
