* 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 > /proc/acpi/video/NVID/LCD/brightness"
}}}
where 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
