Vendor IDs can be found under the /proc/pci. Most modules do actually
give the option of loading with a certain vendor id if they support more
than one chipset.
A more reliable thing you can do is check to see which card was loaded
by comparing /proc/pci with /proc/asound/cards, both of which list
unique characteristics that can be used to determine if a card was
loaded (or if more than one was loaded, etc). Just to be
clear, /proc/pci lists everything on your PCI bus. /proc/asound/cards
lists all cards for which you have loaded modules.
This technique could easily generalize to also checking other buses,
such as USB, firewire, or CardBus.
I wonder if any of the hardware detection systems use this approach
(looking through proc to see what turned up)?

Hi,
just for fun and for learning the system, I wanted to write a
small script which automatically configures any soundcards
(similar to alsaconf).
Based on PCI, I wanted to get all vendor and card IDs and
modprobe each ALSA module to each card found and check the
result.
Unfortunately, this doesn't seem to be that easy. Could anyone
confirm, that I cannot load a module to a certain PCI card?
Furthermore, modprobe does not give any error when probing a
module for a card I do not have.
And I found no way to get backwards the card ID for a loaded
module :( .
Does anyone know a way how I can find out which cards are in
the system and which module fits to it?
Any wee small hint is very welcome.
Best regards
