I can confirm that doing the following fixes the issue for me: ==== 8< ==== # cat </lib/firmware/t540p.fw [codec] 0x10ec0292 0x17aa2210 0 [pincfg] 0x16 0x21211010 0x19 0x21a11010 EOF # cat </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!
