You need to blacklist the card you do not want. How to do that is described here: https://wiki.archlinux.org/index.php/Ad … Sound_Card

it doesn't work for me. Both cards are using same module (hda-intel), and BIOS doesn't support to disable one of them although alsa wiki recommends.

Re: how to disable the 2nd sound card when boot up

I believe that section is referring to when a S/PDIF video card is installed not the HDMI port.  Looking at your aplay the second sound card is for when you have a HDMI device plugged into it.
