But:
!!HDA-Intel Codec information
!!---------------------------
--startcollapse--

Codec: Realtek ALC888
Address: 0
AFG Function Id: 0x1 (unsol 1)
Vendor Id: 0x10ec0888

So I fail to see where the Nvidia MCP77/78 HDMI comes in. My suggestion
would be to rename to:

"[Natty] Realtek ALC888 0x10ec0888 - mic not functional"

Also, have a look here for anything else related:
<https://launchpad.net/+search?field.text=0x10ec0888>
<https://launchpad.net/+search?field.text=0x10ec0888+%2Bmicrophone&field.actions.search=Search>

Other possible assistance:

Again, good luck as sound/mic issues can be tough to resolve.
