    # dmesg | grep -i atl1c

    [    6.052602] atl1c 0000:07:00.0: version 1.0.1.0-NAPI

## Sound

This computer is using the CA0132 chipset. Alsa should work out of the box except for some bugs.

For those using 3.8 kernel note that card sometimes will do random noise that can be fixed by reloading the corresponding module saying that buffer position should be fixed:

    # rmmod snd_hda_intel
    # modprobe snd_hda_intel position_fix=1

If you lose sound after system wake you can recover it by rebooting into Windows and booting Linux again. This may have to do with a firmware problem. There is also no headphone detection.

In kernel 3.9 firmware problem seems to be fixed and headphone detection is working (If speakers do not automute go to alsamixer and unmute HP/Speaker Auto Detect). A lot of channels and fx were added to alsa. Automute only works with the one headphone and microphone jack and not with the earphones jack. This should be reported.

## Touchpad

Works out of the box. See Synaptics

## Video

Since kernel 3.5, PRIME technology is officially supported by the Nouveau graphic drivers. This means that the Nvidia Optimus GPU used in this computer is supported. You need to install bumblebee to let vgaswitcheroo disable your graphics card.

In kernel 3.7 power managing methods were added, so battery life increased a lot.

Kernel 3.10 is coming with a lot of fixes in the Nouveau driver for our NVE0 (Kepler) graphics card. We are expecting a lot of power management improvements.

## Control of the light colors

Supported by alienware-kbl a software to manage the light colors with a graphical interface, python or bash commands.

## BIOS

Current latest version is A12 from InsydeH20.

The updater provided by Dell is windows only. If you want to update and you do not have Windows I recomend you using HirensBoot CD and Unetbooting for creating an Windows Live USB in order to flash the bios.

It contains the flasing utility and the update file (isflashWin.bin). WARNING: This file should not be used with the DOS flashit utility! As it seems this file is an MSDOS executable file which holds LZMA data inside. I could never get it working.
