Linux operating system sound card driver installation and configuration

The general sound card driver is support for windows, linux is very small, so installing the sound card driver is very troublesome. Linux installed sound card driver, using alsa, it is like a versatile, can support many types of sound card, such as:

Installation steps: 1. Unzip the first three things. After decompression, the folder will be generated. For example: folder - alsa-driver, alsa-lib, alsa-untils 2. Open the terminal and enter the alsa-driver file first. Folder, then enter ... 
 (1.. /configure (2, make (4,. /snddevices3, enter the alsa-lib folder, and then enter the content in addition to the 4th in the second item Don't do anything else, business as usual. 4. Enter the alsa-untils folder, everything is the same as the third item. After the above operations are completed, the system files are modified. There is a moudules.conf file in the /ect directory. Join:

Azalia controller --ALC880 ALC882 ALC260 ALC262 ALC883 ALC885 ALC888--- Intel ICH6 ICH7 ---------snd-hda-intel--- ATI chipset -----snd-atiixp-- AC97 controller --ALC655 ALC650 ALC250 ALC255--- Intel ICH6 ICH7 , SiS 7012 and NVidia----------snd-intel8x0--- Via8233 Via686a - ------------------------------ snd-via82xx--- ATI Chipset ------------ ------------------- snd-atiixp according to their actual situation and then modify their own snd-xxxx changed to the corresponding name. Ok, save and restart, generally OK. The first operation is very troublesome, but getting used to it will make it a pleasure, at least I think so. Note: If it is the first operation, you need to modify some things to the system itself. It is recommended to back up first. It is easier to change it when you change it. Backup is actually copying the same thing to another safe place.
