Alsa not detecting my soundcard

Question

So my onboard sound-card died and I bought a new small usb one.

With windows it works perfectly, but on my debian testing not so much.

It isn't detected by my audio system, and I cannot choose the device in the alsamixer application.

Which component of my system handles the soundcard-detection and where should I look for the answer?

EDIT solved:

After I blacklisted snd-hda-intel and rebooted everything worked perfectly out of the box...

Answer 1

> cat /etc/modprobe.d/alsa-base.conf 
options snd_hda_intel index=1
options snd_hda_intel index=2
options snd_usb_audio index=0

There can be only a single options line for one module, so snd-hda-intel ends up with the option index=2.

Options with multiple values must use a single line, with the values separated by commas (index=1,2).

However, for this case, it would be much easier to use the slots option instead:

options snd slots=snd-usb-audio,snd-hda-intel,snd-hda-intel
