I'm trying to get 3 sound cards to be recognised
simultaneously by Windows 2000/Service Pack 4 on
a Pentium 2 with Intel chipset.

I have the following four Creative sound cards:

SB0240 Audigy 2
SB0350 Audigy 2 ZS
SB0350 Audigy 2 ZS
SB0610 Audigy 4

I run the first 3 with kX driver version 5.10.0.3537
and the last with the Creative driver.

I have no other cards installed and have disabled features
so that there are no IRQ conflicts.

I can get any pair of cards to work fine but when I try
any 3, Windows detects 3 for input but only 2 for output.
It doesn't matter which PCI slots I use.

When I try all 4, it detects 4 for input and 2 for output.

All the software I have which displays a list of i/o,
including my own use of the midiOutGetNumDevs() and
midiOutGetDevCaps() functions, displays the same symptoms
so I think Windows' database is wrong.

I've uninstalled/reinstalled the drivers but it makes
no difference. Has anyone else seen/fixed this?
