According to what BIOS says, you have three mics, and the current HDA driver only enables two of them. Perhaps this can be tweakable by user_pin_configs?

Can you please try the following:

1) Make sure you have the latest drivers installed, according to https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules

2) Execute the following commands:

sudo echo 0x0e 0x411111f0 > /sys/class/sound/hwC0D0/user_pin_configs
sudo echo 1 > /sys/class/sound/hwC0D0/reconfig

Try both mics and see if they're working.
