Realtek ALC883 audio chipset (ATI/Intel HD audio)

asoundconf output

dmesg output

It may also be prudent to note that I went through the sources to find all of the “model=” options for the driver for my chipset, and I did try them all, as well as the “model=ref” option. None of these options changed the behavior of the card in any noticeable fashion, though the mixer controls changed (but the new options that showed up with some of the options failed to do anything useful, as well).

Try model=6stack-dig

As I noted above, I tried all of the possible options, and none of them
helped. The exact models I tried are (from
linux-source-2.6.20/sound/pci/hda/patch-realtek.c starting at line 132):

/* ALC883 models */
enum {
        ALC883_3ST_2ch_DIG,
        ALC883_3ST_6ch_DIG,
        ALC883_3ST_6ch,
        ALC883_6ST_DIG,
        ALC883_TARGA_DIG,
        ALC883_TARGA_2ch_DIG,
        ALC888_DEMO_BOARD,
        ALC883_ACER,
        ALC883_MEDION,
        ALC883_LAPTOP_EAPD,
        ALC883_AUTO,
        ALC883_MODEL_LAST,
};

... AND I tried the model=ref option, which is not in this list but is
elsewhere in the source, which can be found by (whitespace edited to
wrap better):

mbt@sage:/usr/src/linux-source-2.6.20/sound/pci/hda$ grep ref *|grep \"
patch_sigmatel.c: { .modelname = "ref",
patch_sigmatel.c: { .modelname = "ref",
patch_sigmatel.c: { .modelname = "ref",
patch_sigmatel.c: { .modelname = "ref",
patch_sigmatel.c: { .modelname = "ref",
patch_sigmatel.c: "available, default to model=ref\n");
patch_sigmatel.c: "available, default to model=ref\n");
patch_sigmatel.c: "available, default to model=ref\n");
patch_sigmatel.c: "available, default to model=ref\n");
mbt@sage:/usr/src/linux-source-2.6.20/sound/pci/hda$

I can't remember the place in the source that maps the constants defined
to the strings used for model=, but they are as you can probably see
above close enough to see what the strings are for the options.

  Thanks,
  Mike

You've fallen victim to trying every model - even ones that are irrelevant to your HDA codec. For instance, you don't have a Sigmatel codec; you have a Realtek one. model=ref is useless since its pin configuration is not even defined for your Realtek codec. What you need to do is pull down alsa-driver 1.0.14 from www.alsa-project.org and try the model that I noted above.

Alrighty, I can try the .14 version again; hopefully, it will give me
diff. results than .14-RC4 did.

Will report back with status after installing/testing.

No change in behavior—“front” still controls ALL volume, and when I plug
in headphones, it still does not sense it. The only thing that adding
that option does is prevent the following message from appearing in the
kernel ring buffer:

[ 16.964000] hda_codec: Unknown model for ALC883, trying auto-probe
from BIOS...

Thanks for the idea to try the new ALSA though. It would appear that it
is still an open issue.

Hi all,

Coming into this discussion a but late, however I have the same problem. I am installed alsa v1.0.14 and am running 2.6.20-16-generic. I do not have headphone jack detect in my volume control->switches and plugging in the headphone jack does not mute the main speakers. I have attached relevant stats. If there is more info needed, let me know. I am a newb when it comes to troubleshooting linux audio so bear with me (am willing to try anything:). I have a MSI L745 laptop by the way.

Thanks,
Adam

Jack sense was previously working, but died after the last kernel upgrade in gutsy. Always trouble with hda-intel.

Was wondering if any headway was being made or if any more information was needed on this issue. It is still not working properly, and wasn't as of a few days ago in Gutsy Tribe 5, either.

Same problem on a HP Pavillion dv9533eg Notebook using a Conexant CX20549 chipset

I can't remember wether the problem was fixed by an upgrade or by myself, but jack sense is currently working for me on kernel 2.6.22-12-generic.

Jack sense still is not working on the hardware that I originally reported the problem with, in the Gutsy Gibbon distribution.

I think that there is some capability missing in the ALSA driver to sense all of the ports that my system has. The switchover on this hardware is definitely a "soft" switch, because when the system is booted up in Vista, there is lag between the time that I plug the headphones in and the time that the main speakers become muted and the headphone port gets sound.

When running under Gutsy, sound just goes to all ports, all the time.

I wonder; if I were able to identify the chips in use for the sound system on this motherboard, would that help for the driver to be improved to handle it? The only that that I know /for sure/ is that it's the chipset that is in the HP Pavilion Slimline s7700n PC. I am attaching the output of lshal. Maybe that will have enough information, but if it doesn't, and more information is still needed, I am open to attempting to provide what I can.

I've read somewhere this problem should be fixed in the current dev versions of alsa, but I don't get the hda-intel module built correctly.

try http://ubuntuforums.org/showpost.php?p=3475485&postcount=235

works for building the alsa module but new alsa version didn't fix the headphone problem

did you add the model=hp thingy to the /etc/ modprobe.d/alsa-base file and restart?

yes, I did but nothing changed.

perhaps it's necessary: My hp notebook has 2 headphone jacks.

see this <http://ubuntuforums.org/showthread.php?p=3475485>

didn't fix it in any way...

by the way: I had to add snd-emu10k1 to /etc/modules to fix snd_hda_intel: Unknown symbol snd_hwdep_new error

Fixed the problem by adding

SND_PCI_QUIRK(0x103c, 0x30cf, "HP DV9553EG", CXT5045_LAPTOP),

to patch_conexant.c in alsa-drivers.

See http://punischdude.styleblogs.de/2007/11/17/audio-jack-sense-on-hp-notebooks/ for details.

Made a bugreport in the alsa bugtracker, too. Hope this will get into upstream next few days/weeks

Same problem, same resolution (even the same IDs) as given by Tobias Stegmann (many thanks!) on HP Pavillion DV6500, applied over ALSA 1.0.15 final from sources. Reported upstream: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3671.

Anybody with a MSI laptop got it working correctly?

I have the problem solved with model=lenovo-nb0763
my system
fujitsu-siemens amilo pi 2515
and audio codec is Realtek ALC883
cat /proc/asound/card0/codec#* | grep Codec
Codec: Motorola Si3054
Codec: Realtek ALC883

ubuntu Linux 7.10 kernel 2.6.22-14-generic
alsa-base version 1.0.14-1ubuntu2
and options line set to
options snd-hda-intel model=lenovo-nb0763
in /etc/modprobe.d/alsa-base
check http://www.mjmwired.net/kernel/Documentation/sound/alsa/ALSA-Configuration.txt#850 for ALC883 possible models

try http://ubuntuforums.org/showpost.php?p=3475485&postcount=235

upgrading to ubuntu 8.04 beta or even 7.10 in some cases solves this issue.

newer ubuntu versions fix issue.

This issue is not fixed—I just tested this on Hardy with the hardware that I originally reported the issue on, out of the box and fully updated, and jack sense still does not work.

Reverting to "Confirmed" status. This is something that does work in "that other system", though it seems that it is done by seeing some sort of message from the hardware, which then shuts off the output to the rear speakers.

Note that there are three relevant mixer switches for volume when using 5.1 speakers; the one labelled "Front" by ALSA is what also seems to control the headphone volume, though the headphone volume for the jack on the front of the machine and the ports on the back are two separate things and can (at least in Windows Vista) be controlled separately.

I receive the same error:

hda_codec: Unknown model for ALC883

but my sound works fine? I'm running Hardy beta with latest updates.

I confirm Michaels bug report. When I plug in my headphones, main audio is NOT muted. I have an ALC882, which is correctly detected. I'm running Hardy with all recent updates applied.

Reporting that for Asus x55sv laptop the solution was to add the line
options snd-hda-intel model=lenovo-101e
to /etc/modprobe.d/alsa-base
I spent hours trying to track down the relevant thread and then trying every option from ALSA-Configuration.txt file (linked above by someone). Thanks to everyone who posted their experiences!

Running Ubuntu 8.04 with stock alsa (alsa-base version 1.0.16-0ubuntu)

I can confirm this bug on Kubuntu 8.04 64 bit, Asus V1S. I have had this issue since 7.10 and tried all options on https://help.ubuntu.com/community/SoundTroubleshooting on 7.10.

Same problem on the Sony Vaio VGN-SZ650N. Sound from speakers, but can't detect headphone jack. Hardy Heron 8.04, all updates.

I had this problem on a Fujitsu Siemens Amilo computer. I solved the problem by installing the latest Alsa driver (see instructions at https://help.ubuntu.com/community/HdaIntelSoundHowto). Maybe this is unnecessary. Then I used cat /proc/asound/card0/codec\#*|grep Codec with result

Codec: Motorola Si3054
Codec: Realtek ALC883

then went to http://www.mjmwired.net/kernel/Documentation/sound/alsa/ALSA-Configuration.txt and searched for ALC883 and found many options. Luckily, someone else tried them for me; and found that adding

options snd-hda-intel model=acer

to the end of the file /etc/modprobe.d/alsa-base

and restarting the computer fixes the problem. I found that, finally, the contents of gnome-volume-manager changed and that the headphones were working!

I dunno but I think 8.04 resolves this issue. It did for me at least.

Is this symptom still reproducible in an 8.10 alpha 6 desktop image?

My sigfile ran away and is on hiatus.

This bug is still reproducible in intrepid with latest updates

I've got a Realtek ALC883 in my Fujitsu Amilo Pi 2550. Today I installed a fresh 64bit 8.10 RC followed by all updates and not only were my laptop speakers not muting when I plugged in some headphones but I had no independent control of either. I fixed both problems by editing /etc/modprobe.d/alsa-base and adding the line:

options snd-hda-intel model=fujitsu-pi2515

To the end as it was the nearest model to mine.

Wasn't sure on whether to start a new bug report or not as it is pretty much same problem as above except its a different make/model laptop and a later Ubuntu involved of course.

This bug still existed in Jaunty and latest upgrades, however following comment #41 fixes the problem.
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/114053/comments/41

This sympton still exists for me in Karmic Koala (9.10) with alsa 1.0.20

dutchy@vampire:~$ cat /proc/asound/card0/codec#* | grep Codec
Codec: Realtek ALC883

I've added my model, options snd-hda-intel model=6stack-dig but this did not resolve the problem

I can confirm this. After an upgrade to Karmic, I still can't make any input source work and no jack detection occurs on an ALC883 chipset.

alejandro, please use staging.launchpad.net if you want to try out Launchpad's functions.

Please, if you're accessing them from a question on Launchpad, tell us what number solved your problem, or tell us if your problem persists. This document is based on http://drowninginbugs.blogspot.com/2009/10/caveats-for-audio-in-910.html

[0] First of all, apply the updates, nothing more. Maybe your problem has already been resolved without you having to do anything else. Before following the guide and after updating, reboot and so aplicna you ensure that all changes.

[1] Make sure you are using the kernel and not the old Karmic. Run "uname-r". It should say 2.6.31-14-generic or higher. If you get an older version, you may be using an older kernel. Ask for your case.

[2] Make sure slmodemd is not running. Run "pgrep slmodemd. You should not give back anything. If you return something, ask about your particular case.

[3] Install linux-backports-modules-alsa-karmic-generic.
    sudo apt-get install linux-backports-modules-alsa-karmic-generic
Then reboot and see if the sound and run better. If he says that this package does not exist, go to System »Administration» Software Sources. In the Updates tab active "Unsupported Updates (karmic-backports)". Click close and when prompted if you want to reload package information say yes. Then try installing again.

[4] Add the PPA of Ubuntu Audio Development Team and maintained.
    sudo apt-add-ppa repository: ubuntu-audio-dev/ppa
    sudo apt-get update
    sudo apt-get dist-upgrade
Packages should be updated alsa and pulseaudio. then reboot and see if that fixes your problem.

[5] Get a PulseAudio log with these instructions: https: / / wiki.ubuntu.com / PulseAudio / Log
Get also a log of ALSA with these instructions: https: / / wiki.ubuntu.com / DebuggingSoundProblems # Automatic% 20sound% 20Information% 20Collection
Http://paste.ubuntu.com/ paste both logs in and passes the addresses to a question so people can see your particular case and try to help.

alejandro #58 you made my day,
sudo apt-get install linux-backports-modules-alsa-karmic-generic
that's all i had to do, i don't understand why it is not installed by default..

@Victor: linux-backports-modules-alsa-karmic-generic is not as much tested as the original module, so we are afraid it will break the sound support for other people if we install it by default.

So, this is a real oldie. Michael B. Trausch, you're the original bug reporter, is this still a problem for you with the latest Ubuntu release?
