[SOLVED] XFCE4 changes the assignment of sound card when booting

I did a fresh install of Arch and XFCE4. My system has an Intel sound card:

[david@archdavid ~]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: MID [HDA Intel MID], device 0: VT1828S Analog [VT1828S Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: MID [HDA Intel MID], device 2: VT1828S Alt Analog [VT1828S Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: MID [HDA Intel MID], device 3: VT1828S Digital [VT1828S Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

So I created the corresponding .asoundrc:

[david@archdavid ~]$ cat .asoundrc 
pcm.!default {
    type hw
    card 1
}

But randomly, I realized that when I boot my system I don't have sound! In that case, the output of aplay -l is the following:

[david@archdavid ~]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: MID [HDA Intel MID], device 0: VT1828S Analog [VT1828S Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: MID [HDA Intel MID], device 2: VT1828S Alt Analog [VT1828S Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: MID [HDA Intel MID], device 3: VT1828S Digital [VT1828S Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

This change in the output of aplay -l happens without plugging anything else to my system.

What is the reason for changing the number of assignment to my sound card?

Thanks in advance.

Re: [SOLVED] XFCE4 changes the assignment of sound card when booting

Drop .asoundrc and use options snd-hda-intel index=0 in /etc/modprobe.d/modprobe.conf to ensure HDA Intel MID is the first card on every boot. Reboot after apply the setting.

Read the wiki page on ALSA.
