I installed ubuntu 14.04 on my xps 13 (non touchscreen). The current kernal is 3.16.0-49, and bios is version A05. I have wifi and the trackpad working, but the mic no longer does. Does anyone know how to fix this? Thanks

The Dell XPS 9343 microphone is currently broken on kernel 3.16.


You have to use kernel 3.19 which contains a fix for the microphone.

There are two ways to do it :

  1. Manually install kernel 3.19 on your current Ubuntu installation.

    sudo apt-get install linux-headers-generic-lts-vivid linux-image-generic-lts-vivid
    
  2. Upgrade to Ubuntu 15.04 (which has kernel 3.19).
    I wrote a full guide on how to do it on this laptop.

Something that worked for me (on Ubuntu 16.04 with kernel 4.4.0-87) was to install pavucontrol and set it as the 'fallback' on the input devices tab. It seems that the default audio settings controller in Ubuntu 16.04 wasn't picking up the internal mic properly, but pavucontrol spotted it fine (the levels were jumping when I made noise), and I just needed to set it as the default (fallback?).I got the idea from here even though I am not using archlinux.
