I guess quirks for the pins leading to the external dock jack are missing.
It seems the missing quirk is the same as for the T440: http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/?id=1c37c...
Applying the pin config at module load time fixes the problem for me.
This hotfix as suggested by Jim Minter in: https://bugzilla.redhat.com/show_bug.cgi?id=1101386#c11 is

So, alsa devs, could you please enable ALC292_FIXUP_TPT440_DOCK for ThinkPad L440 (codec 0x17aa, 0x501e)?
Sure, could you check the patch below?
