A little help. No more random detection of soundcard

Pals, good evening.

Reading this on arch wiki

Set the default sound card

First you will have to find out the card and device id that you want to set as the default by running aplay -l:

$ aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: Conexant Digital [Conexant Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: JamLab [JamLab], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: Audio [Altec Lansing XT1 - USB Audio], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

For example, the last entry in this list has the card ID 2 and the device ID 0. To set this card as the default, you can either use the system-wide file /etc/asound.conf or the user-specific file ~/.asoundrc. You may have to create the file if it does not exist. Then insert the following options with the corresponding card and device id.

~/.asoundrc

defaults.pcm.card 2
defaults.pcm.device 0
defaults.ctl.card 2

The 'pcm' options affect which card and device will be used for audio playback while the 'ctl' option affects which card is used by control utilities like alsamixer .

The changes should take effect as soon as you (re-)start an application (mplayer etc.).

If your sound card order changes on boot, you can specify their order in /etc/modprobe.d/modprobe.conf. For example, if you want your mia sound card to be #0:

/etc/modprobe.d/modprobe.conf

options snd slots=snd_mia,snd_hda_intel
options snd_mia index=0
options snd_hda_intel index=1

snd_mia and snd_hda_intel are the modules used by the respective cards. This configuration assumes you have one mia sound card and one card using snd_hda_intel (e.g. onboard). These changes require a system reboot.

A doubt came.....

these are my sound cards

well, I need that  [ADC Capture/Standard PCM Playback] be the first playing sound card, cause USB audio is a LP turntable, don't plays audio

On arck wiki, it says put my config on modprobe.conf, but my arch don't have this file
-> should I create?
-> And how does I put the keys on this file? How should be this file on my case?

I were doing this file, but, I stopped when the doubt came

options snd slots=emu10kx,snd_hda_intel
options emu10kx index=0
options snd_hda_intel index=1
