[alsa-devel] No sound on Thinkpad T440s in Docking Station

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...?

Please find alsa-info.sh output attached.
