Multiple Sound card , how do I load the modules in the same order every boot?

I have tried to use /etc/modprobe.d/alsa-base.conf to set the order.

The issue that I am having is that two devices use the same module:

cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_ctxfi
 2 snd_hda_intel
 3 snd_usb_audio
 4 cx88_alsa

cat /proc/asound/cards
 0 [SB             ]: HDA-Intel - HDA ATI SB
                      HDA ATI SB at 0xfe800000 irq 16
 1 [XFi            ]: SB-XFi - Creative X-Fi
                      Creative X-Fi 20K2 SB0880
 2 [NVidia         ]: HDA-Intel - HDA NVidia

 3 [U0x46d0x807    ]: USB-Audio - USB Device 0x46d:0x807
                      USB Device 0x46d:0x807 at usb-0000:00:13.2-3.2, high speed
 4 [CX8801         ]: CX88x - Conexant CX8801
                      Conexant CX8801 at 0xfb000000
I want the first two device to always be index 0 and 1.

I can't figure out how to specify the correct snd_hda_intel device for index 0.

I did find this in the alsa wiki for multiple cards of the same type:
options snd-usb-audio index=1,2 vid=0x0ccd,0x0d8c pid=0x0028,0x000c

However I am not able to find the vid/pid info for these.

I am running Linux Mint 13.

Any help will be appreciated . thanks

BTW, I have spend hours googling and reading , just haven't found anything that works.

I suspect that udev is the way forward here. Have you investigate that approach?

Use an approach similar to the one used for the Nics in this thread, but adapt them to your sound cards;
