Solution
=======
I reboot to a live cd (http://www.playoss.com/node/179)
mount internal hdd
download http://packages.debian.org/firmware-linux-nonfree
and extract the radeon to {mount-directory-of-debian-root}/lib/firmware

No sound on Realtek ALC269VB under Linux
As of 30/09/2011, ALC269VB is not the support model listed in
www.realtek.com/downloads/downloadsview.aspx?langid=1&pfid=24&level=4&conn=3&downtypeid=3
I thought it must be a key (e.g. laptop-amic) to define in /etc/modprobe.d/alsa-base.conf
for the sound card to work properly like
https://help.ubuntu.com/community/HdaIntelSoundHowto
and http://siripong-computer-tips.blogspot.com/2011/07/82801i-vostro-v13-debian-no-sound.html
After hours of trial and error changing snd-hda-intel model=auto, basic, asus
and reboots, there were no sounds from Realtek ALC269VB of ASUS X43B Series.
Finally, I found that the root cause was that
"the modern video-cards have an little audio support built-in, for HDMI.
In some cases, ALSA misunderstand where is the 'main' sound hardware".
From http://www.linuxquestions.org/questions/slackware-14/no-sound-with-flash-player-in-firefox-after-adding-nvidia-gt-220-graphics-card-809773/

Solution
======
The solution is simply set the default PCM device.
How to do that
===========
Big Thanks to: http://alsa.opensrc.org/.asoundrc
# Using aplay -L you can get a List of existing PCM output devices.
$ aplay -L
....
front:CARD=SB,DEV=0
HDA ATI SB, ALC269VB Analog
Front speakers
......
# To set the default device, place a pcm.!default line in the .asoundrc
$ echo 'pcm.!default front:SB' > ~/.asoundrc
While aplay is still error, there are sounds from vlc and iceweasel.
$ aplay /usr/share/sounds/alsa/Noise.wav

I thought it must be a key (e.g. laptop-amic) to define in /etc/modprobe.d/alsa-base.conf
for the sound card to work properly like
https://help.ubuntu.com/community/HdaIntelSoundHowto
and http://siripong-computer-tips.blogspot.com/2011/07/82801i-vostro-v13-debian-no-sound.html
After hours of trial and error changing snd-hda-intel model=auto, basic, asus
and reboots, there were no sounds from Realtek ALC269VB of ASUS X43B Series.
Finally, I found that the root cause was that
"the modern video-cards have an little audio support built-in, for HDMI.
In some cases, ALSA misunderstand where is the 'main' sound hardware".

Solution
======
The solution is simply set the default PCM device.
How to do that
===========
Big Thanks to: http://alsa.opensrc.org/.asoundrc
# Using aplay -L you can get a List of existing PCM output devices.
$ aplay -L
....

......
# To set the default device, place a pcm.!default line in the .asoundrc
$ echo 'pcm.!default front:SB' > ~/.asoundrc
While aplay is still error, there are sounds from vlc and iceweasel.

==========
Disable nomodeset, the Live usb will not hang.
The newest kernels have moved the video mode setting into the kernel. So all the programming of the hardware specific clock rates and registers on the video card happen in the kernel rather than in the X driver when the X server starts.. This makes it possible to have high resolution nice looking splash (boot) screens and flicker free transitions from boot splash to login screen. Unfortunately, on some cards this doesnt work properly and you end up with a black screen. Adding the nomodeset parameter instructs the kernel to not load video drivers and use BIOS modes instead until X is loaded.http://askubuntu.com/questions/207175/what-does-nomodeset-do

sudo iwconfig wlan0 channel {channel number}
# WEP encryption
sudo iwconfig wlan0 key {hex digit}
#eg: sudo iwconfig wlan0 key 0123-4567-89
sudo iwconfig
# dhclient -r : to avoid "RTNETLINK answers: File exists" when reconnect network after standby or hibernate
sudo dhclient -r wlan0
sudo dhclient wlan0
sudo ifconfig wlan0
To avoid soft blocked again after reboot add
options ath_pci rfkill=0
options ath_pci rfkill=1
options ath_pci rfkill=2
... (depend on rfkill list)
to /etc/modprobe.d/ath.conf
(any new file with .conf extension)
or
insert 'rfkill unblock wlan' in /etc/rc.local
ifup - ifdown
==========
# my /etc/network/interfaces is
auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet dhcp
auto wlan0
iface wlan0 inet dhcp
wpa-ssid my_ssid
wpa-psk my_password_shared_key
wpa-key-mgmt WPA-PSK
# now we can bring our interface up and down with the usual ifup and ifdown commands
sudo ifup wlan0
sudo ifdown wlan0
# The "auto" stanza will bring your interface up at system startup.
# If not desired, remove or comment this line.
wpa useful command
