Solution: no front sound output or sound input in Fedora14

The computer is very powerful (you can hear a lot, but you can't understand it). After using windows for a long time, you will know how to play games. I heard that Linux is very powerful, but it is not very easy to use, and many games cannot be used. In order to hone yourself and play games less, I decided to start using Linux. After some setbacks, I successfully installed Fedora, And now I use version 14! Just installed a video card. You can watch Youku's fire shadows in 3D! The disadvantage is that you can only enable speakers when watching videos. There is only one sound output interface, which is very troublesome (sometimes with headphones to avoid disturbing others ). So we started our journey of installing sound cards.

So I started my journey of installing a sound card. I had a lot of detours (which reminds me of the long journey), checked a lot of information, and wrote my success method below:

First, install the Fedora kernel documentation: kernel-doc (view a lot of stuff to use)
Yum install kernel-doc
Go to/usr/share/doc/kernel-doc- // Documentation/sound/alsa/ALSA-Configuration.txt
Find the module that supports your sound card. I use HD Audio and snd-hda-intel, which is already available in Fedora 14.
Generally, the module cannot be correctly detected, so you must set the correct mode:
Go to/usr/share/doc/kernel-doc- // Documentation/sound/alsa/HD-Audio-Models.txt
Find the motherboard chip or the corresponding mode. The chip I use is ALC883, 3 interfaces, 2 front, www.linuxidc.com so I chose 3stack-2ch-dig mode. Okay. The preparation is complete. Now the problem is officially solved.
Open terminal: su
Cd/etc/modprobe. d
Vi alsa. conf
Enter the following content:
Options snd-hda-intel model = 3stack-2ch-dig
Save and exit ESC
: Wq
Restart the computer, enter the sound properties, and select a suitable device. I am the last one. You can try it one by one.
