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 have a Dell laptop thats fairly new. Ive got RH9 on and working pretty well. The only problem is my headphone slot. No matter what mixer settings I use, or any other settings I change, nothing works. I know its not a bad slot or speakers becaue it works in XP. Has anyone else had this problem?
First of all, are you sure you are running ALSA? I understand RH does not use that by default.
New laptop might be bad news for standard packaged distro. It's hard for the driver writers to keep up with the flood of new hardware. Try to find the exact type of sound chip and google it against 'linux', 'redhat', 'RH9' or 'alsa'. Also check the ALSA web site (www.alsa-project.org).
ALSA seems a good bet with new hardware, but some people seem to have a lot of trouble installing it.
Knoppix live CD is a painless way to try out ALSA, if you can get one.
I should have said this before but the laptop speakers work like they should. XMMS, Xine, System sounds, etc. work fine. The problem is when I hook in the headphones. My lsmod looks like this (with non sound stuff omitted)
Also strange is the fact that there is no actual driver in that lsmod list that I can recognise. Still, if the built-in speakers are working... But didn't you have to choose a driver when you installed ALSA?
I suppose you have tried unmuting and turning up all possible channels in alsamixer, as well as googling for your specific notebook model along with 'linux' and/or 'alsa'?
I did google for my specific laptop (Dell inspiron 8500) and found a site with a custom ACPI kernel and RPM alsa drivers. Also, I have checked the alsamixer, and everything that can be up is up. However, there are some things that can't be turned up anyway.
Okay. Thanks for your help everyone that tried. This is part of the reason I love Linux. I dont have to call some 20 cents a minute or pay per solution tech support line and get some guy in his house. Thanks again.
