Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Pls I just installed Kubuntu 7.10 then I tried all the multimedia tools available starting with AMarok but there is no sound all what I have is the message:Audio output unavailable; the device is busy.
Probably you have a soundcard with only one channel (typical for cheap integrated cards on the motherboard), and some other program is hogging that card. First, check the sound server is OFF (K menu -> system settings -> Sound system -> uncheck the "enable the sound system" checkbox). Youo may need to log out and back in again for the change to be effective.
Another thing to check is that there are no esd processes running. esd is the enlightenment sound demon and is sometimes started by some programs which use it to connect to the sound card. Sadly, they often leave the process attached to the soundcard when they terminate, and on single channel cards this can get in the way of other programs. Here's how to check and remedy this problem:
Open a terminal
In the terminal, enter the command:
ps aux |grep esd |grep -v grep
If you get any lines back, get the PIDs (second column) of the esd process(es), and then pass them as a parameter to kill, e.g. if you found an esd process with PID 12345, execute this command:
Run the ps command again to confirm the esd processes are dead.
The same message persists to show even when AMAROK is started at the bash prompt and the message is: QString::arg(): Argument missing: <p>Audio output unavailable; the device is busy.<p>xine parameters:<i></i>, cdda:/1
I had unchecked "Enable the sound system" and run the "ps aux|grep esd|grep -v grep" but no process was return on the terminal. Also under the system settings I tried "test sound" then I heard nothing. But when I started the Amarok on the terminal so also a process started called "ruby" and I don't know what it means.
Sorry, I have been away for a while; but the command:
sudo lsof | grep dsp
returns nothing to the terminal and everytime that I start Amarok the error message comes out with something related to "Xine parameters". So I am thinking if the problem has something to do with "alsa". When I run Adept there are several packages of "alsa" that are not installed and I do not no which one I should installed or what not. So is it possible that the error message has something to do with "alsa"?
What I realized was the no sound card was installed on my system and I don't know how to install one since I don't even have it listed with the commands that I have tried. My system is Dell latitude d830 if you have any further assistance to make.
