Laptop snd-hda-intel no head phone audio fix for Arch

For:

[joel@moo modprobe.d]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC269VB Analog [ALC269VB Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The output above means that my audio is using card 0. This means I need to alias card 0 and slot 0. This is my modeprobe.conf:

#
# /etc/modprobe.d/modprobe.conf
#
#disable autoload of ipv6
alias net-pf-10 off

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=auto

After you add those critical last three lines and reboot, if it still doesn't work you should try doing this below:

"That is likely a problem with the dump of the ALSA state. Remove the
file "/var/lib/alsa/asound.state" and run "/etc/rc.d/alsa stop" after
that. Then the current state is dumped into a fresh file and the error
should be gone."
