How to install sound driver in linux ubuntu 14.04?

Question

linux

Good day . I searched on the Internet for information on how to solve the problem with sound in ubuntu, and so, I did not find it. I decided to download the drivers for my sound system, downloaded it, but I don’t understand how to install it. There is an instruction in English. More or less I understand, but not all. I ask for help

Installation:
This Source Code is from www.alsa-project.org.
For OS installation, please remember add the Development tool kit.
For driver installation, please follow below steps. 

Automatic install: (Recommend RedHat distribution)
execute

  ./install

Note: Ubuntu OS, please use manual install.
      Run commands need to add sudo at first words.   

Manual install:
Step 1. unzip source code
        tar xfvj alsa-driver-1.0.xx.tar.bz2

Step 2. Turn on sound support from kernel config 
  (soundcore module, default turn on)

Step 3. Complied source code
  a. cd alsa-driver-1.0.xx
  b. ./configure
  c. make
  d. make install
  e. alsaconf
  f. ./snddevices (Only kernel 2.4 does it)

Step 4. Edit your /etc/modules.conf or conf.modules depending on the distribution
 	(Please refer to the attached modules.conf)
   
        snd-xxxx is the card ID.

  -- Azalia controller --ALC880 ALC882 ALC260 ALC262 ALC883 ALC885 ALC888
     --- Intel ICH6 ICH7 ---------
               snd-hda-intel

        -- AC97 controller --ALC655 ALC650 ALC250 ALC255
           --- Intel ICH6 ICH7 , SiS 7012 and NVidia----------
               snd-intel8x0
           --- Via8233 Via686a  -------------------------------    
         snd-via82xx
           --- ATI Chipset  -------------------------------
         snd-atiixp

        Copy and paste this to the bottom of your /etc/modules.conf or /etc/modprobe.conf file.
  # ALSA portion
          alias char-major-116 snd
          alias snd-card-0 snd-xxxx     
        # OSS/Free portion
          alias char-major-14 soundcore
          alias sound-slot-0 snd-card-0
        # card #1
          alias sound-service-0-0 snd-mixer-oss
          alias sound-service-0-1 snd-seq-oss
          alias sound-service-0-3 snd-pcm-oss
          alias sound-service-0-8 snd-seq-oss
          alias sound-service-0-12 snd-pcm-oss

Step 5. reboot your machine

Step 6. Use the alsamixer the disable mute (All audio line default is mute)
        *Must to compile and to install the ALSA library and utility. (Use automatic install is already install)
        excute alsamixer

Note: 	1. The most detail information, can refer the alsa-kernel/Documenttation/ALSA-Configuration.txt in the azx-021705.tar.bz2.
  2. Kernel Version must be 2.2.14 or later.
  3. All mixer channels are muted by default. You must use a native
    or OSS mixer program to unmute appropriate channels.
  4. If can not compile the source code, try to rename the /usr/src/linux-2.x -> /usr/src/linux.
  5. The driver added to support the SPDIF functoin. 	
  6. a. You can download the alsa-lib-1.0.9 and alsa-utils-1.0.9a form the www.alsa-project.org, then unzip and install them. 
     b. Suggest use "alsamixer" to control mixer function.
     c. Used "alsaconf" can autodetect which drive you need to install (step 4). 	
        7. SUSE Distribution must install the ncurses package
