Greetings,

I have this emachines em350 notebook, which is equipped with ALC272X
codec (a personal project this time...)
By default the internal mic does not work.
(See also https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/639846)

I need some hints about how to either find the right model, or write a
quirk for hda-intel using the following information.

thanks & regards

Eliot Blennerhassett.

Using hda_analyzer, The internal mic appears to be a digital mic on NID 12
This change enables it:

According to the ALC272 datasheet, there is no feedthrough path from
DMIC to analog o

Some of the other controls for this netbook are also superfluous.
It only has (as far as I can make out)
Internal speaker on NID 0x14 (LOUT1 PORT-D)
Internal mic: DMIC on NID 0x12 (DMIC-1/2)
External headphone on NID 0x21 (HP-OUT PORT-I)
External mic on NID 0x18 (MIC1 PORT-B)
