Can anyone tell me in what sequence audio devices are enumerated for XP?  For 
example, we use a system with 64 channels of audio (32 devices) on four PCI 
cards. (A bunch of audio)  These devices normally enumerate starting with the 
first PCI card slot and so on until the last card's device.

This enumeration sequence is listed in the control panel for example under 
audio devices.  This is also the sequence that they are enumerated using 
DirectSound to enumerate devices.

My questions are:  What determines the sequence?  Can I guarantee that device 1 
on PCI card 1 will always be in the enumeration sequence before the next card, 
etc.?  For example, we can use third party audio cards with our system also, 
which can add to the total number of devices.  (As you know, there is a limit 
of 32 devices in XP)
