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.

I thought my sound subsystem was fine until I tried installing Skype. System is Mandriva 10.2 (upgraded from 10.1 and 10.0) with a nforce 2 integrated sound chip. My microphone plays fine through the speakers but I don't get any sound in Skype and on chasing the probem around I also don't get any recorded sound using arecord.
Other interesting but maybe relavant stuff:
I don't have any /dev/dsp or /dev/mixer.
I don't have any /dev/sound devices
I do use udev and it has got the following devices under /dev/snd but i don't know what they are or do...

When running skype from the terminal I get a read error on /dev/dsp (not surprisingly), when running it with "artsdsp -m /usr/bin/skype" it runs fine except no audio from the mic. and artsdsp complains about no /dev/mixer.
All oss emulation modules appear loaded ok.
I get a boot error message complaining about lack of mixer settings. KDE 3.3 appears to have normal mixer controls and they appear to be working ok.
