I run Ubuntu 10.10 on my Intel DG965RY. My front audio ports don't work in Ubuntu, the rear one does. I never got it working earlier when I had Ubuntu 10.04 but this time I am going to try it again.

My codec is SigmaTel STAC9227

My ALSA information is here.

Handy details:

!!ALSA Version
Driver version:     1.0.23
Library version:    1.0.23
Utilities version:  1.0.23

!!Loaded ALSA modules

I know something that I will have to change the model of my module to make the front audio jack works but I couldn't find a model related line in my ALSA configuration file - /etc/modprobe.d/alsa-base.conf (I was able to get to that point in Ubuntu 10.04, may be something has changed).

How can I proceed from here?

Edit: Module details:

Module snd-hda-intel

    Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8, ICH9, ICH10,
            PCH, SCH),
        ATI SB450, SB600, R600, RS600, RS690, RS780, RV610, RV620,
            RV630, RV635, RV670, RV770,
        VIA VT8251/VT8237A,
        SIS966, ULI M5461

    [Multiple options for each card instance]
    model    - force the model name
    position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF)
    probe_mask  - Bitmask to probe codecs (default = -1, meaning all slots)
              When the bit 8 (0x100) is set, the lower 8 bits are used
          as the "fixed" codec slots; i.e. the driver probes the
          slots regardless what hardware reports back
    probe_only    - Only probing and no codec initialization (default=off);
          Useful to check the initial codec status for debugging
    bdl_pos_adj    - Specifies the DMA IRQ timing delay in samples.
        Passing -1 will make the driver to choose the appropriate
        value based on the controller chip.
    patch    - Specifies the early "patch" files to modify the HD-audio
            setup before initializing the codecs.  This option is
        available only when CONFIG_SND_HDA_PATCH_LOADER=y is set.
        See HD-Audio.txt for details.
    beep_mode    - Selects the beep registration mode (0=off, 1=on, 2=
        dynamic registration via mute switch on/off); the default
        value is set via CONFIG_SND_HDA_INPUT_BEEP_MODE kconfig.

    [Single (global) options]
    single_cmd  - Use single immediate commands to communicate with
        codecs (for debugging only)
    enable_msi    - Enable Message Signaled Interrupt (MSI) (default = off)
    power_save    - Automatic power-saving timeout (in second, 0 =
    power_save_controller - Reset HD-audio controller in power-saving mode
        (default = on)

    This module supports multiple cards and autoprobe.

    See Documentation/sound/alsa/HD-Audio.txt for more details about
    HD-audio driver.

    Each codec may have a model table for different configurations.
    If your machine isn't listed there, the default (usually minimal)
    configuration is set up.  You can pass "model=<name>" option to
    specify a certain model in such a case.  There are different
    models depending on the codec chip.  The list of available models
    is found in HD-Audio-Models.txt

    The model name "genric" is treated as a special case.  When this
    model is given, the driver uses the generic codec parser without
    "codec-patch".  It's sometimes good for testing and debugging.

    If the default configuration doesn't work and one of the above
    matches with your device, report it together with alsa-info.sh
    output (with --no-upload option) to kernel bugzilla or alsa-devel
    ML (see the section "Links and Addresses").

    power_save and power_save_controller options are for power-saving
    mode.  See powersave.txt for details.

    Note 2: If you get click noises on output, try the module option
        position_fix=1 or 2.  position_fix=1 will use the SD_LPIB
        register value without FIFO size correction as the current
        DMA pointer.  position_fix=2 will make the driver to use
        the position buffer instead of reading SD_LPIB register.
        (Usually SD_LPIB register is more accurate than the
        position buffer.)

    NB: If you get many "azx_get_response timeout" messages at
    loading, it's likely a problem of interrupts (e.g. ACPI irq
    routing).  Try to boot with options like "pci=noacpi".  Also, you
    can try "single_cmd=1" module option.  This will switch the
    communication method between HDA controller and codecs to the
    single immediate commands instead of CORB/RIRB.  Basically, the
    single command mode is provided only for BIOS, and you won't get
    unsolicited events, too.  But, at least, this works independently
    from the irq.  Remember this is a last resort, and should be
    avoided as much as possible...

    MORE NOTES ON "azx_get_response timeout" PROBLEMS:
    On some hardwares, you may need to add a proper probe_mask option
    to avoid the "azx_get_response timeout" problem above, instead.
    This occurs when the access to non-existing or non-working codec slot
    (likely a modem one) causes a stall of the communication via HD-audio
    bus.  You can see which codec slots are probed by enabling
    CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec
    proc files.  Then limit the slots to probe by probe_mask option.
    For example, probe_mask=1 means to probe only the first slot, and
    probe_mask=4 means only the third slot.

    The power-management is supported.

Possible models for my codec:

  ref        Reference board
  ref-no-jd    Reference board without HP/Mic jack detection
  3stack    D965 3stack
  5stack    D965 5stack + SPDIF
  5stack-no-fp    D965 5stack without front panel
  dell-3stack    Dell Dimension E520
  dell-bios    Fixes with Dell BIOS setup
  volknob    Fixes with volume-knob widget 0x24
  auto        BIOS setup (default)

Unfortunately, I don't have much idea of putting them to use.


I tried every model listed for my codec but still couldn't get it to work.

options snd-hda-intel model=ref
options snd-hda-intel model=ref-no-jd
options snd-hda-intel model=3stack
options snd-hda-intel model=5stack
options snd-hda-intel model=5stack-no-fp
options snd-hda-intel model=dell-3stack
options snd-hda-intel model=dell-bios
options snd-hda-intel model=volknob
options snd-hda-intel model=auto

I tried them one by one by putting it at the end of config file

sudo gedit /etc/modprobe.d/alsa-base.conf

After every change I force-reload alsa

sudo alsa force-reload

  • Does that confirm it as a bug? – Ashfame Jan 4 '11 at 20:42
  • I have the same problem with the SigmaTel STAC9274D (my motherboard is an Intel DX38BT), until now I failed to find the source of the problem. The funny thing is that the fron jacks are working fine on Ubuntu 8.10. – user10763 Feb 13 '11 at 17:27

    This question seems abandoned, there is not further information or activity added to it for several months. I am flagging this to be closed by a moderator. If you think this issue is still affecting you you can flag a moderator to re-open it. – Bruno Pereira Feb 6 '12 at 16:38

I have exactly the same problem with exactly the same SigmaTel STAC9227 (though my motherboard is DQ965GF). I managed to get one of the front audio ports to work - the microphone. It started working after I applied '3stack' option. But you need to change the settings in your 'sound preferences' > 'input' > 'connector' should be set to 'microphone 2'. But I haven't been able to make the front audio output to work with any of the options as you stated. We'll have to dig deeper for the solution I guess :(
