If your card is correctly detected by alsa, you will see it in
/proc/asound/cards, e.g.:

$ cat /proc/asound/cards
 0 [IXP            ]: ATIIXP - ATI IXP
                      ATI IXP rev 1 with unknown codec at 0xb0003400, irq 17
 1 [Modem          ]: ATIIXP-MODEM - ATI IXP Modem
                      ATI IXP Modem rev 1 at 0xb0003800, irq 17
 2 [Audio          ]: USB-Audio - USB Audio
                      USB Audio at usb-0000:00:13.0-2, full speed

Most sound related programs can be configured to use a particular
sound card.

With the example above

$ alsamixer -c 2

controls the sound card with index 2 (the USB one).

You can also configure alsa to use a particular sound card as the
default, see the alsa documentation.
