[SOLVED] No sound after massive upgrade

Question

Hello,
I'm just writing to ask for some information about my problem. Recently I upgraded my ArchLinux system after a while without doing it.
My surprise came when, after rebooting my system is without sound. No sound anywhere. Both the speakers and the volume are turned up at the maximun and there's still no sound.
I would appreciate any information you could give me to solve this problem which is killing me.
Also say that before the upgrade the sound was working perfectly.
Here's my rc.conf file:
# /etc/rc.conf - Main Configuration for Arch Linux
# LOCALIZATION
# LOCALE: available languages can be listed with the 'locale -a' command
# HARDWARECLOCK: set to "UTC" or "localtime", any other value will result
# in the hardware clock being left untouched (useful for virtualization)
# TIMEZONE: timezones are found in /usr/share/zoneinfo
# KEYMAP: keymaps are found in /usr/share/kbd/keymaps
# CONSOLEFONT: found in /usr/share/kbd/consolefonts (only needed for non-US)
# CONSOLEMAP: found in /usr/share/kbd/consoletrans
# USECOLOR: use ANSI color sequences in startup messages
LOCALE="es_ES.UTF-8"
HARDWARECLOCK="UTC"
TIMEZONE="Europe/Madrid"
KEYMAP="es"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"

# MOD_BLACKLIST: Prevent udev from loading these modules
# MODULES: Modules to load at boot-up. Prefix with a ! to blacklist.
# NOTE: Use of 'MOD_BLACKLIST' is deprecated. Please use ! in the MODULES array.
MOD_AUTOLOAD="yes"
#MOD_BLACKLIST=() #deprecated

# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it
# - no hyphens in your interface names - Bash doesn't like it

# Wireless: See network profiles below
#Static IP example
#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
eth0="dhcp"
INTERFACES=(eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
# Enable these network profiles at boot-up. These are only useful
# if you happen to need multiple network configurations (ie, laptop users)
# - set to 'menu' to present a menu during boot-up (dialog package required)
# - prefix an entry with a ! to disable it
# Network profiles are found in /etc/network.d
# This now requires the netcfg package
#NETWORKS=(main)
# DAEMONS
# Daemons to start at boot-up (in this order)
# - prefix a daemon with a ! to disable it
# - prefix a daemon with a @ to start it up in the background
DAEMONS=(vboxdrv syslog-ng dkms_autoinstaller !network !netfs dbus @wicd @alsa kdm @crond preload openntpd)
Thanks

This is what I tried the first but everything seems okey:
DSpider wrote:$ speaker-test -c 2
speaker-test -c 2
speaker-test 1.0.25
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 2048 to 16384
Period size range from 1024 to 1024
Using max buffer size 16384
Periods = 4
was set period_size = 1024
was set buffer_size = 16384
0 - Front Left
1 - Front Right
Time per period = 5,632541
0 - Front Left
1 - Front Right
Tried it also, but no sound in the speakers.

My sound card stopped working today after I updated. I was surprised because my soundcard always worked before. My music player (audacious) said something like "No audio device available".
I had to reboot 2 times. After that, my sound card worked again. I don't know why.
I don't know if you have the same problem as me, but we both had a similar problem on the same day doing the same thing (working sound card -> update -> no sound). Maybe it's just a coincidence?
What a shame but that was not the solution, my computer has been rebooted more than twice since then and still no sound
