here’s a quick way to get the microphone working on the Adamo / Adamo XPS.

1. run “arecord -l” in the terminal, the output should be something like this:
   

   **** List of CAPTURE Hardware Devices ****
   card 0: Intel [HDA Intel], device 0: ALC269 Analog [ALC269 Analog]
     Subdevices: 1/1
     Subdevice #0: subdevice #0
   

2. Note the device chipset number (mine was ALC269) and look up the proper model keyword from this list
3. put the following lines in “/etc/modprobe.d/alsa-base.conf”
   

   options snd-hda-intel model=basic enable=1 index=0
   options snd-hda-intel enable_msi=1
   

   replace “basic” with the model keyword that matches your chipset model from the list above

4. run:

   sudo service module-init-tools restart
   

and that’s it! your mic should work fine now :)

note: you might want to unmute the mic from sound settings before you use it with an app like skype
