Default How and when are the sound modules loaded at system boot time on CentOS 5?

That is how the kernel loads a module when insmod is run - but what
tells the system to load the sound modules at system start-up?

I have a system with 2 sound 'cards', one on the motherboard and one on
a PCI-E card. Both cards use the Intel HDA chipset (snd-hda-intel.ko
driver). When the on-board card has been disabled via a jumper, none of
the sound modules get loaded at system start-up. I can manually load the
snd-hda-intel module and the PCI-E card is found.

Therefore, I would like to find out why the PCI-E card is not found and
the driver not loaded at system start-up. Hence my original question, if
anyone knows at what point in the start up procedure the system loads
the sound modules.
