Originally in 2.6, the kernel was equipped with ALSA sound card driver, and there was sound when the system was installed. The driver was 1.0.11. Sound is there, but the built-in speakers come out, the external will not sound, depressed. I looked at it online and said it was about to update the driver. Today I spent one night upgrading the driver ....
Looking at the http://www.alsa-project.org, the latest stable version is 1.0.13 and there is a 1.0.14rc2 in the test. Install 1.0.13 first. The official version is safer.
Downloaded driver, Lib, utils, decompressed, and compiled from driver
#./Configure
# Make & make install
Both of the first two are normal. When utils is reached, the ncurses library is missing ....
Update ncurses: sudo apt-Get install ncurses-base ....
# Make & make install
It seems everything is normal, reboot!
After the reboot, the installation was successful, but the external speaker still had no sound ....
Isn't the driver New enough ????
Then download 1.0.14rc2!
Install ....
Reboot ....
Depend! I still can't. I'm depressed. I'm still depressed. How can I do it ????
Final Solution:
1. Change the plug to a jack. Try it on your own.
2. Select 6ch for channel mode !!!!
..... In this way, you can use it. It's depressing ....
P.s. You can use the lspci | grep audio command to view the sound card. Mine is:
00: 1b. 0 audio device: Intel Corporation 82801fb/FBM/fr/FW/FRW (ich6 family) high definition Audio Controller (Rev 04)
I don't know if the next driver will solve this bug ....
