bien detallado y para tomarse un tiempo.

Pero, hacé una cosa por favor, mandanos la salida de pcinfo.sh 
(ejecutalo con sudo o como root), y le mando el reporte directamente 
a la gente de ALSA, así nos dan una respuesta bien concreta. salu2

 | Gracias

 |
 | Booting
 |
 | If your boot hangs on loading the module for snd-hda-intel, try
 | disabling the card in your BIOS. It is called "HD Audio
 | Controller", "Azalia Audio" or similar. Then try solving the
 | problem using the instructions below.
 |
 | Identify the Problem
 |
 | Most cards seem to work as of Ubuntu 6.06 LTS using the stock
 | kernel. However, the following problems might occur on some
 | setups:
 |
 |     * No sound at all
 |     * Low volume output
 |     * High pitched noise
 |     * Poor sound quality
 |     * Sound disappears when touching volume controls
 |     * Sound works at random after each reboot
 |     * No mic working
 |     * Sound only plays through headphones
 |
 | Solution for Apple Macs
 |
 | In case of slightly distorted, weird, crackled sound on Apple Macs
 | it have been reported by several users, that unload snd_hda_intel
 | module at boot time and then reload it, can help to get rid of
 | crackled sound. For do this, edit /etc/rc.local by typing in
 | Terminal
 |
 | sudo gedit /etc/rc.local
 |
 | And add two following lines to the end of file before "exit 0":
 |
 | rmmod snd_hda_intel
 | modprobe snd_hda_intel
 |
 | Update to the Latest Version of ALSA
 |
 | These instructions do not interfere with the Ubuntu package
 | structure or other kernel modules - in other words, the changes
 | seem drastic however they are simply adding greater functionality
 | to an existing kernel module (Please read the Caveats section!)
 |
 | I would call the above untrue - i rebooted to no sound and a few
 | hours of messing around to fix it (thanks to
 | [SoundTroubleshooting]). [PaulOppenheim]
 |
 |     * Install the required tools and kernelheaders
 |
 | sudo aptitude install build-essential libncurses-dev gettext
 | linux-headers-`uname -r`
 |
 |     * Install your kernel headers
 |     *
 |
 |       Download the latest version of alsa from Alsa project
 | (driver, lib, and utils) to a directory (eg. ~/downloads). In the
 | following we assume that the latest version is 1.0.14. Please
 | change this in accordance with the one you downloaded from the
 | Alsa project site. o
 |
 |             alsa-driver
 |           o
 |
 |             alsa-lib
 |           o
 |
 |             alsa-utils
 |     * Setup installation directories
 |
 | sudo mkdir -p /usr/src/alsa
 | cd /usr/src/alsa
 | sudo cp ~/downloads/alsa* .
 | sudo tar xjf alsa-driver*.bz2
 | sudo tar xjf alsa-lib*.tar.bz2
 | sudo tar xjf alsa-utils*.tar.bz2
 |
 |     * Compile and install alsa-driver
 |
 | cd alsa-driver*
 | sudo ./configure --with-cards=hda-intel
 | --with-kernel=/usr/src/linux-headers-$(uname -r) sudo make
 | sudo make install
 |
 |     * Compile and install alsa-lib
 |
 | cd ../alsa-lib*
 | sudo ./configure
 | sudo make
 | sudo make install
 |
 |     * Compile and install alsa-utils
 |
 | cd ../alsa-utils*
 | sudo ./configure
 | sudo make
 | sudo make install
 |
 | Note that you must have the curses library installed to be able to
 | compile alsa-utils. You can install it with this command from a
 | terminal: sudo apt-get install libncurses5-dev
 |
 |     * Reboot
 |     * if you have no sound, run dmesg and look for the string
 | "snd_"
 |
 | Manually Specify Module Parameters
 |
 |     * First you must find which model of sound card you use, so
 | run this command:
 |
 | cat /proc/asound/card0/codec#* | grep Codec
 |
 | It will return model of your sound card(s), for example: "Codec:
 | Realtek ALC260", so your sound card is ALC260.
 |
 |     * You should open a file in ALSA documentation. This file is
 | here (replace KERNEL_VERSION with your kernel's version!):
 |
 | /usr/src/KERNEL_VERSION/Documentation/sound/alsa/ALSA-Configuratio
 |n.txt
 |
 | If you didn't have this file, for version 2.6.22, you can check
 | out this link or you can find ALSA-Configuration.txt in the
 | subdirectory /alsa-kernel/Documentation/ of the alsa-driver-1.x.x
 | directory you created.
 |
 |     * Search for your model, and take a look at its types, for
 | example I found the following lines for ALC260:
 |
 | hp              HP machines
 | hp-3013         HP machines (3013-variant)
 | fujitsu         Fujitsu S7020
 | acer            Acer TravelMate
 | basic           fixed pin assignment (old default model)
 | auto            auto-config reading BIOS (default)
 |
 | Read all of them and try to find the one which is more similar to
 | your sound card, for example if you have a laptop, you can choose
 | "acer".
 |
 |     * Open /etc/modprobe.d/alsa-base with the following command:
 |
 | sudo nano /etc/modprobe.d/alsa-base
 |
 | Then paste the following line at the end of the file (change MODEL
 | with the type of sound card's model, in our example it should be
 | "acer" (without quotation marks)):
 |
 | options snd-hda-intel model=MODEL
 |
 |     * Reboot
 |
 | Playing with probe_mask
 |
 | Another possible option is the 'probe_mask' parameter, which has
 | been known to fix sound issues characterized by the occurrence of
 | "azx_get_response timeout" messages reported with 'dmesg'. Try
 | either "probe_mask=1" or "probe_mask=8" by adding a line like:
 |
 | options snd-hda-intel probe_mask=1
 |
 | Choosing Your Model
 |
 | The full list of models is available in ALSA-Configuration.txt in
 | the subdirectory /alsa-kernel/Documentation/ of the
 | alsa-driver-1.0.14 directory you created. Note that this list is
 | ordered on modules and codec chips. To find your codec use this
 | command from a terminal:
 |
 | cat /proc/asound/card0/codec\#*
 |
 | If one of those worked but was not autodetected, you can help the
 | alsa developers by sending them the output of lspci -nv and the
 | model you used on Alsa BTS.
 |
 | Extra Hints to Get Sound Working
 |
 | Wrong mixer in use: Sometimes the volume control chooses the OSS
 | mixer if the compatibility module is loaded. You may need to right
 | click on the volume control applet in your gnome-panel and go to
 | the preferences and change the device to the one called Alsa
 | Mixer. The same applies to the gnome volume control program.
 |
 | Mixer doesn't seem to work: The HD Audio standard has many output
 | channels. As a result, the correct volume sliders might not be
 | visible. Enable the volume sliders through Edit->Preferences in
 | gnome volume control.
 |
 | No mic working, rest OK: After installing and configuring the
 | Intel-SigmaTel STAC 9205 soundcard in my DELL Latitutde D630 as
 | described above, I could use xmms to play sound on this machines.
 | The microphone did, however, not work. To make the mic work as
 | well, I booted Win XP on the same machine, plugged the microphone
 | in and selected Microphone instead of the menu items "Line-In" or
 | "No action" in the Intel-SigmaTel event window. That event window
 | was opened by the Win XP soundcard driver when I plugged in the
 | microphone. I then booted ubuntu 7.04 with alsa-driver-1.0.15-rc3
 | and used alsamixer to make the following changes: Front-Gain:
 | 94<>94, both Input Sources = Front Mic, then pressed F4 and set
 | the 2 captures to 100<>100 and to 93<>93. Eventually, I pressed
 | Esc to end alsamixer and save my changes. After these steps, I
 | could use arecord -f cd out.wav to record sound using my
 | microphone. BTW, I used "options snd-hda-intel model=auto" as the
 | last line of /etc/modprobe.d/alsa-base for this particular
 | soundcard and OS.
 |
 | Troubleshootinng
 |
 | dmesg shows "disagrees about version of symbol" and "Unknown
 | symbol" for snd_ctl_add, etc
 |
 | if you reboot and have no sound, and check dmesg to find:
 |
 | [ 1058.932000] snd_hda_intel: disagrees about version of symbol
 | snd_ctl_add [ 1058.932000] snd_hda_intel: Unknown symbol
 | snd_ctl_add
 | [ 1058.932000] snd_hda_intel: disagrees about version of symbol
 | snd_pcm_new [ 1058.932000] snd_hda_intel: Unknown symbol
 | snd_pcm_new
 | [ 1058.932000] snd_hda_intel: disagrees about version of symbol
 | snd_pcm_limit_hw_rates [ 1058.932000] snd_hda_intel: Unknown
 | symbol snd_pcm_limit_hw_rates [ 1058.932000] snd_hda_intel:
 | disagrees about version of symbol snd_card_register [ 1058.932000]
 | snd_hda_intel: Unknown symbol snd_card_register
 |
 | ... etc. then you need to do a few extra steps.
 |
 | ubuntu default snd-hda-intel.ko location:
 | /lib/modules/2.6.22-14-generic/ubuntu/media/snd-hda-intel/snd-hda-
 |intel.ko
 |
 | alsa 1.0.15's installation location:
 | /lib/modules/2.6.22-14-generic/kernel/sound/pci/hda/snd-hda-intel.
 |ko
 |
 | so copy
 | /lib/modules/2.6.22-14-generic/kernel/sound/pci/hda/snd-hda-intel.
 |ko to
 | /lib/modules/2.6.22-14-generic/ubuntu/media/snd-hda-intel/snd-hda-
 |intel.ko .
 |
 | and put the modules/* in alsa's compile directory into
 | /lib/modules/.../kernel/sound, you can use "find" to get their
 | location. snd-hda-intel.ko snd-hwdep.ko snd.ko snd-mixer-oss.ko
 | snd-page-alloc.ko snd-pcm.ko snd-pcm-oss.ko snd-rtctimer.ko
 | snd-seq-device.ko snd-seq.ko snd-seq-midi-event.ko snd-seq-oss.ko
 | snd-timer.ko
 |
 | then, depmod -a
 |
 | reboot, try again.
 |
 | (Thanks to forum user pcmanlin on this ubuntu forum thread)
 |
 | alsa-utils don't compile
 |
 | If you have trouble compiling alsa-utils simply run
 |
 | alsactl -v
 |
 | and it will show you the installed version. Check on
 | http://www.alsa-project.org/ if your card is supported in that
 | version and download the source packages. Go back to the "Setup
 | installation directories" step above and try again.
 |
 | Caveats
 |
 | Overwriting packaged files and adding unmanaged files by running
 | sudo make install may break upgrades. A better way is to create a
 | backport by using the build scripts from your current alsa source
 | packages. This would also allow you to undo the changes if they
 | don't work, by simply downgrading back to the original package
 | version.
