Notes

note 1
the sound doesn't work after resume from standby (suspend to ram)
workaround:
1. stop the sound deamon ('artsd' under KDE)
2. run
```
sudo rmmod snd_hda_intel
sudo modprobe snd_hda_intel
```
3. restart the sound deamon
note 2
driver 'nv' (xserver-xorg-video-nv 1:2.1.8-1ubuntu1):
- adjusting brightness through Fn+up/down works fine but without 3D acceleration
driver 'nvidia' (nvidia-glx-new 169.12+2.6.24.12-16.34):
- display brightness is always at minimum level after boot
- when booting with AC adapter plugged in the display switches from max. brightness to min. brightness when the bootmessage * Loading hardware drivers...
  is displayed
- after resume from standby (suspend to ram) the brightness is at maximum level
- brightness adjustment isn't possible when driver 'nvidia' is loaded
  this seems to be a known problem at NVidia (http://www.nvnews.net/vbulletin/showthread.php?t=100494)
  workaround:
  1. switch to an other vt (e.g. Ctrl+Alt+F6)
  2. run
```
sudo sh -c "echo -n <level> > /proc/acpi/video/NVID/LCD/brightness"
```
    where <level> is 0, 10, 25, 40, 55, 70, 85 or 100
note 4
channel 'Mic' (Mic Jack) is always used as source for recording no matter what channel was selected (tested with audacity and gnome-sound-recorder; alsa-lib 1.0.15-3ubuntu4)
note 5
passing channel 'front Mic' (Internal Mic) to the speakers through KMix (enable output channel 'Front Mic') works.
note 6
input channel 'capture 1' has to be enabled for recording
