You were right. Sorry, I didn't understand in code what you were saying.
By inspecting the Router code more closely, I clarified that I should
have done what you said...

The only difference from what you said is that I didn't call Build*
function from DllMain function, as by calling from there the application
hangs on a call to alcGetString from Creative driver (I don't know why).
I maintained the initialization of device listings and strings on
alcGetString, alcOpenDevice and alcCaptureOpenDevice, as you can see in
the attached patch. The most important change was to break out the
BuildDeviceList() function into SearchImplementation(),
BuildDeviceList(), BuildCaptureDeviceList() and BuildAllDevicesList().

Please check out the patch against the r1789 from Creative OpenAL
repository for Router files.
