I was able to find the default pin configurations in the .INI file, but 
have not yet understood what the rest of the stuff in the .INI file 
means (and I haven't really looked at any .INF files).  If you know of 
any guides to help understand the SigmaTel-codec related contents of an 
INI/INF file I would be happy to look at that.  I do see stuff like

[HKLM\SOFTWARE\SigmaTel\STSysTray\1.0\EventExpressions\JackPresensec]
Action1="if(JackState(10) == 0 && JackState(15) == 0 && JackState(12) == 
0 && GetPortPopup(12) == 1,(SetDeviceType(10,2)),(0))"
Action2="if(JackState(10) == 0 && JackState(15) == 0 && JackState(12) == 
0 && GetPortPopup(12) == 1,(SetDeviceType(15,2)),(0))"
Action3="if(JackState(10) == 0 && JackState(15) == 0 && JackState(12) == 
0 && GetPortPopup(12) == 1,(SetDeviceType(12,8)),(0))"

which could hold the key to what I'm looking for...

Thanks.
