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,
