Ubuntu to compile the sound card driver, solve the external speakers problem!

Originally in 2.6 in the kernel is with ALSA sound card driver, loading system is also a sound, drive is 1.0.11. Sound is there, but the built-in speakers out of the outside, the outside is not a sound, depressed. Look at the Internet, it is said to update the driver, today night, just to upgrade the driver ....
Look at the http://www.alsa-project.org, the latest stable version is 1.0.13, there is a test in the 1.0.14RC2. Then put 1.0.13, the official version is more safe, hehe.
Download the Driver,lib,utils and start the compilation from driver after decompression
#./configure
# Make && make install
The first two are normal, when the utils in./configure time, the hint said what ncurses library missing ....
and to update Ncurses:sudo apt-get install Ncurses-base ....
# Make && make install
It seems that everything is normal, reboot.
It is true that the installation was successful after the reboot, but there is still no sound on the external speakers ....
is not the drive enough new ....
And then to download the 1.0.14RC2.
Installation....
Reboot .....
By. Or not, depressed, and now still depressed, in the end how to acridine ....


Final Solution:
1. Change the plug for a jack, try it yourself.
2. Channel Mode must choose 6CH ....
。。。。。 This can be used, depressed death ....
P.s. Casually speaking, you can use LSPCI | grep Audio command to look at the sound card, my is:
00:1b.0 Audio Device:intel Corporation 82801fb/fbm/fr/fw/frw (ICH6 Family) high Definition Audio Controller (rev. 04)
Don't know if the next driver will solve the bug ....
