This is my /etc/modprobe.d/alsa-base.conf. It ensures that USB mics get index 0 - otherwise chromium cannot use them as audio source - and my builtin cards (Nvidia HDMI, soundblaster, onboard sound) are 1/2/3. Last line shows how to deactivate all but the last internal card and give it the index 1.
$ cat /etc/modprobe.d/alsa-base.conf #options snd_hda_intel model=thinkpad options snd_usb_audio index=0 options snd_hda_intel index=1,2,3 #options snd_hda_intel index=3,2,1 enable=0,0,1

Try /etc/modprobe.d/alsa.conf (that's the standard location, I believe).
$ cat /etc/modprobe.d/alsa.conf cat: /etc/modprobe.d/alsa.conf: No such file or directory
Ah, no, you don't have these files. That file /etc/modprobe.d/alsa-base.conf is what I use to configure my soundcards. You can use it as it is to place the usb sound device on index 0 and sb on index 1. Or you can experiment with the entries - e.g. with those that I commented out.
