[Sound input] Removnig one of two sound cards.


in terminal :

$ cat /proc/asound/cards
 0 [Tegra          ]: HDA-Intel - HDA NVIDIA Tegra
                      HDA NVIDIA Tegra at 0x70038000 irq 113
 1 [II             ]: USB-Audio - Voice Tracker II
                      Acoustic Magic Voice Tracker II at usb-tegra-xhci-3, full speed

I’m trying to use a software that uses a microphone i’m getting this error

----- Failed to open audio device "hw:CARD=0,DEV=0" -----

seems like it uses Card=0 by default. which isn’t a microphone.
how to disable card 0?
