Hello,

I'm getting the same issue reported by Joschi in May, but with a docked T540p.  I can confirm that doing the following fixes the issue for me:

==== 8< ====
# cat <<EOF >/lib/firmware/t540p.fw
[codec]
0x10ec0292 0x17aa2210 0

[pincfg]
0x16 0x21211010
0x19 0x21a11010
EOF

# cat <<EOF >/etc/modprobe.d/hda-intel.conf
options snd-hda-intel patch=t540p.fw,t540p.fw,t540p.fw
EOF

Then rmmod/modprobe the snd-hda-intel kernel module, or just reboot.
==== 8< ====

I can see http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/?id=1c37c22332a2d2c1b4ab32177a4f847c7fe06e38 which I presume resolves this problem for T440s and T440p users.

Please could an additional line, I'm guessing as follows, be added to sound/pci/hda/patch_realtek.c to include T540p users in this happy group?

+	SND_PCI_QUIRK(0x17aa, 0x2210, "Thinkpad T540p", ALC292_FIXUP_TPT440_DOCK),

Thanks!

Jim
