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.
