hda_codec: Unknown model for ALC268

hda_codec: Unknown model for ALC268

[Stefanie]

Hello!

I have problems with the sound chip of my notebook. It is a Medion akoya
WIM 2220. Actually, there is a driver for the chip, but somehow, I can't
get it to work. I'm desperate and don't know what to do.

My friend helped my to gather the following information:

This is from lspci:

00:1b.0 0403: 8086:284b (rev 04)

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 04)
        Subsystem: Wistron Corp. Device 4085
        Flags: fast devsel, IRQ 22
        Memory at fa200000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+
Count=1/1 Enable-
        Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
        Capabilities: [100] Virtual Channel <?>
        Capabilities: [130] Root Complex Link <?>
        Kernel modules: snd-hda-intelk <?>
 
I have found this in my syslog while trying to load snd-hda-intel:

Jan 10 21:30:16 Mescalin HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22

Thanks in advance for your help.

Hi Stefanie,

There are some pre-defined models for ALC268:

static const char *alc268_models[ALC268_MODEL_LAST] = {
        [ALC267_QUANTA_IL1]     = "quanta-il1",
        [ALC268_3ST]            = "3stack",
        [ALC268_TOSHIBA]        = "toshiba",
        [ALC268_ACER]           = "acer",
        [ALC268_ACER_DMIC]      = "acer-dmic",
        [ALC268_ACER_ASPIRE_ONE]        = "acer-aspire",
        [ALC268_DELL]           = "dell",
        [ALC268_ZEPTO]          = "zepto",
#ifdef CONFIG_SND_DEBUG
        [ALC268_TEST]           = "test",
#endif  
        [ALC268_AUTO]           = "auto",
};      

You can try them with commands like

        modprobe snd-hda-intel model=3stack

and report the one works for you, so that we integrate this knowledge
into future kernel versions.

You are also welcome to provide your hardware information by running 
        http://www.alsa-project.org/alsa-info.sh
and upload the data collected by it.

Thanks,
Fengguang

I've loaded the module with different model parameters. Afterwards, I
tried alsamixer. As this didn't work, I used aumix to maximize all
levels. Finally, I used aplay to play some audio files.

"quanta-il1", "toshiba":

from alsamixer:
  ALSA lib simple_none.c:1520:(simple_add1) helem (MIXER,'Headphone
Playback Switch',0,2,0) appears twice or more
  alsamixer: function snd_mixer_load failed: Invalid argument

-works, but hardly audible


"dell":

Too many audio devices

from alsamixer:
  ALSA lib simple_none.c:1520:(simple_add1) helem (MIXER,'Headphone
Playback Switch',0,2,0) appears twice or more
  alsamixer: function snd_mixer_load failed: Invalid argument

-works, but hardly audible


"acer", "acer-aspire":

from alsamixer:
  ALSA lib simple_none.c:1520:(simple_add1) helem (MIXER,'Master
Playback Switch',0,2,0) appears twice or more
  alsamixer: function snd_mixer_load failed: Invalid argument

-nothing audible


"3stack", "acer-dmic", "zepto", "test", and "auto":

  HDA Intel: probe of 0000:00:1b.0 failed with error -16
