Please read this and help how to build the driver step by step.  I cannot understand the step by step installation and most commands do not work.  I am using UBUNTU-9.04.  My driver is C-media.  I got to build driver.  The read me file is not very clear here.  I will write my questions in between the steps that I do not understand pls read and answer with step by step command for ubuntu-9.04.

Read-me file

1. Backup the Config.in and Makefile in the sound driver directory
     (/usr/src/linux/driver/sound).
     The Configure.help provide help when you config driver in step
     4, please backup the original one (/usr/src/linux/Document) and
     copy this file.
     The cmpci is document for the driver in detail, please copy it
     to /usr/src/linux/Document/sound so you can refer it. Backup if
     there is already one.

  2. Extract the tar file by 'tar xvzf cmpci-xx.tar.gz' in the above
     directory.  (kamakoti---Above directory means which directory???)

==> into the /usr/src/linux/driver/sound

  3. Change directory to /usr/src/linux  (kamakoti---where to change and what to change.)

==> in a terminal ("command prompt for linux") type "cd /usr/src/linux"

  4. Config cm8338 driver by 'make menuconfig', 'make config' or
     'make xconfig' command.  (kamakoti--Explain more on these commands step by step.)

==> These are used for helping to choose kernel compilation options.  The easiest one to use is "make xconfig" as it gives you a graphical menu

  5. Please select Sound Card (CONFIG_SOUND=m) support and CMPCI
     driver (CONFIG_SOUND_CMPCI=m) as modules. Resident mode not tested.
     For driver option, please refer 'DRIVER PARAMETER'  (kamakoti--I had not touched this area)

  6. Compile the kernel if necessary.  (kamakoti--help required step by step how to compile)

==> https://help.ubuntu.com/community/Kernel/Compile

  7. Compile the modules by 'make modules'. (kamakoti--help required step by step)

==> It is simply put in the terminal "make modules"  "make" is a command.

  8. Install the modules by 'make modules_install' (kamakoti--help required step by step)


INSTALL DRIVER  (kamakoti--help required step by step)
================================================================================

  1. Before first time to run the driver, create module dependency by
     'depmod -a'

  2. To install the driver manually, enter 'modprobe cmpci'.

  3. Driver installation for various distributions:

    a. Slackware 4.0
       Add the 'modprobe cmpci' command in your /etc/rc.d/rc.modules
       file.so you can start the driver automatically each time booting.

    b. Caldera OpenLinux 2.2
       Use LISA to load the cmpci module.

    c. RedHat 6.0 and S.u.S.E. 6.1
       Add following command in /etc/conf.modules:

       alias sound cmpci

	also visit http://www.cmedia.com.tw for installation instruction.

DRIVER PARAMETER
================================================================================

  Some functions for the cm8738 can be configured in Kernel Configuration
  or modules parameters. Set these parameters to 1 to enable.

  mpu_io:	I/O ports base for MPU-401, 0 if disabled.
  fm_io:	I/O ports base for OPL-3, 0 if disabled.
  spdif_inverse:Inverse the S/PDIF-in signal, this depends on your
		CD-ROM or DVD-ROM.
  spdif_loop:   Enable S/PDIF loop, this route S/PDIF-in to S/PDIF-out
                directly.
  speakers:     Number of speakers used.
  use_line_as_rear:Enable this if you want to use line-in as
                rear-out.
  use_line_as_bass:Enable this if you want to use line-in as
                bass-out.
  modem:	You will need to set this parameter if you want to use
		the HSP modem. You need install the pctel.o, the modem
		driver itself.
  joystick:	Enable joystick. You will need to install Linux joystick
		driver.
