Configure Ubuntu (linux) sound

Hi everyone,

I just installed Ubuntu June 2006 version on my x86 Pentium 4 PC. I have a HUGH problem configuring the sound / multimedia system.

I have a C-Media 9880 sound card manufactured in Taiwan. Currently the Volume Control can let me choose between:

a) C-Media CMI 9880 (OSS Mixer) or
b) HDA Intel (Alsa Mixer)

#4 Ubuntu forum suggested changes: http://ubuntuforums.org/showthread.php?t=44753

I don't how to change file permissions in /etc/esound/ such that I can overrwrite the existing esd.conf with

john@john-desktop:/etc/esound$ chmod u=rwx,g=rwx,o=rwx esd.conf
chmod: changing permissions of `esd.conf': Operation not permitted

john@john-desktop:/etc/esound$ ls -la *
-rw-r--r-- 1 root root 198 2006-07-20 22:23 esd.conf

Desired changes according to Ubuntu forum:
==========================================
# Make /etc/esound/esd.conf look like this:
Code:

[esd]
auto_spawn=1
spawn_options=-terminate -nobeeps -as 2 -d default
spawn_wait_ms=100 # default options are used in spawned and non-spawned mode
default_options=

Q>> Can someone please help me to configure my sound card properly as I am a novice in Unix!!

Many thanks, and take care, John! (jcylo2000@yahoo.com)

Changing system files in Ubuntu

Hi John,

You mentioned that you are a novice - please let me know if you need more details.

In Ubuntu, the preferred method for doing things which require root access is to use the 'sudo' command. This allows you to execute commands as another user. If you don't specify a user name, the sudo executes the command as root.

So, you need to do something along the following lines:
john@john-desktop:/etc/esound$ sudo gedit esd.conf

This should allow you to open the file as root, and therefore have permission to write to the file.

I hope this helps,
Adam
