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=1c37c22332a2d2c1b4ab32177a4f847c7fe06e38
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
# cat >/lib/firmware/tpt440dock-patch.fw <<EOF
[codec]
0x10ec0292 0x17aa501e 0
[pincfg]
0x16 0x21211010
0x19 0x21a11010
EOF
# cat >/etc/modprobe.d/hda-intel.conf <<EOF
options snd-hda-intel
patch=tpt440dock-patch.fw,tpt440dock-patch.fw,tpt440dock-patch.fw
EOF
# rmmod snd_hda_intel
# modprobe snd_hda_intel
So, alsa devs, could you please enable ALC292_FIXUP_TPT440_DOCK for
ThinkPad L440 (codec 0x17aa, 0x501e)?
cheers
sascha
