Dear all,
using openSUSE 13.1 on an Thinkpad T440s, I am not getting sound once the laptop is docked to its docking station.
I suspect an additional SND_PCI_QUIRK is needed for this model. "pactl list" returns
alsa.mixer_name = "Realtek ALC292" alsa.components = "HDA:10ec0292,17aa220c,00100001"
for the analog audio output sink in docked state.
Hence I assume a new line *similar* to this
SND_PCI_QUIRK(0x17aa, 0x220c, "Thinkpad T440s", ALC269_FIXUP_LENOVO_DOCK),
is needed? What about the ALC292 instead of 269 Realtek chip...?
It's a compatible chip, so the codec name doesn't matter. You can try it with model=lenovo-dock option with the recent kernels. For Haswell, it's safer to pass twice (model=lenovo-dock,lenovo-dock).
Let us know if this works for you.

Hi Takashi,
so i have: ------------------ /etc/modprobe.d/50-sound.conf -------------------
options snd-hda-intel model=lenovo-dock,lenovo-dock options snd slots=snd-hda-intel,snd-hda-intel # 3hqH.vsazS+ZIdb9:Intel Corporation alias snd-card-0 snd-hda-intel # u1Nb.8dI5aUgInHB:Intel Corporation alias snd-card-1 snd-hda-intel
and rebooted, but still get no sound from the headphone jack on the dock, although the built-in speakers immediately mute when plugging in headphones.
Give alsa-info.sh output with that state for further checking.
Takashi
Please find alsa-info attached while docking and with "model=lenovo-dock,lenovo-dock" option.
