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. | | CategoryHardware | | HdaIntelSoundHowto (última edición 2008-09-07 11:31:28 efectuada | por rex-lux) © 2007 Canonical Ltd.
