How do I determine sound card type with bash?

Question

In bash, how do I determine what sound card is installed? I'm trying to create a plugin for Rhythmbox, and I'd like to test for this in a configuration script.

Edit: On my machine, I needed to use sudo to be able to use lspci and lsmod. @Quassnoi's answer using cat worked without extra privileges.

Answer 1

lspci | grep -i audio

Answer 2

cat /proc/asound/cards
