No obvious difference (all coefs are the same!), but several things are differing, first, the product name:
-Product Name: 20AMOS3 +Product Name: 20AMZ02QUS Second, even the hardware is of a later revision: -00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 03) +00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04) Second, firmware, kernel and ALSA dkms are all newer on the working one: -Firmware Version: GIET53WW (2.01 ) +Firmware Version: GIET60WW (2.10 ) -Kernel release: 3.13.0-32-generic +Kernel release: 3.13.0-46-generic -[ 15.242582] snd_hda_intel 0000:00:1b.0: Probing card using HDA DKMS, version 0.201502151246~ubuntu14.04.1 +[ 13.866567] snd_hda_intel 0000:00:1b.0: Probing card using HDA DKMS, version 0.201503011031~ubuntu14.04.1 On the non-working one, please try updating both the firmware, the kernel, and the ALSA daily dkms on the non-working one to rule out differences between the non-working and working one. Then post another alsa-info with dump_coef on.

Would you like to continue troubleshooting anyway? However, the System Settings... -> Sound UI shows the mic as not muted. When I tried running the alsamixer command, I saw mic and mic- boost were both showing 0; I cranked them up to 100, but it made no difference. I also tried re-running this command with the mic/mic- boost still set to 100 and it threw the same error.
