[Openal] OpenAL 1.1 alcOpenDevice() fails with Dell M90, WinXP, SigmaTel audio

[Garin Hiebert]

Is this machine able to play audio through the SigmaTel device with any 
other application?  If so, then this is truly odd -- when you try to 
open the NULL device, alcOpenDevice first tries DS3D, then DS, then 
MMSYSTEM.  For all three of those to fail on a Windows setup where 
drivers are installed at all is pretty strange.
