Anyway, if you dont need/use this soundcard (which is the one integrated 
in the mainboard, I suppose), then it should be better to blacklist it.

It means avoid loading the related kernel module.

To see which are the loaded modules do:
$ lsmod

To blacklist the unwanted module (say it is named: 'snd_hda_intel'), add 
the line:
   blacklist snd_hda_intel
to the '/etc/modprobe.d/alsa-base-blacklist.conf' config file.
Another way is:
- create a file '/etc/modprobe.d/snd_hda_intel.conf' containing 
'blacklist snd_hda_intel'
('snd_hda_intel' is just an example... you should use the "right" module 
Run 'depmod -ae' as root (sudo)
Recreate your initrd with 'update-initramfs -u'
(See: https://wiki.debian.org/KernelModuleBlacklisting)

Here some info about fixing the audio setup:
