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'm running fedora 12 on my Asus Z92VA laptop. Everything is running fine, except for the fact that I have no audio on my headphone. When I use the command "alsamixer -c0", there is no listing for the headphone.
When I use the command "cat /proc/asound/card0/codec#* | grep Codec" I get the following output:
Codec: Realtek ALC880
Codec: Conexant ID 2bfa
I have searched several forums, but found no sollution to my problem. Does anyone have any ideas?
Hi Tredegar, thanks for the reply.
I'm just using a Standard audio-jack-socket. I also tried to plug it into other sockets (like the microphone), but no sound. When I plugin the jack in the socket for the headset the sound from the speakers goes to mute.
I'm using gnome and my headphone doesn't need batteries. I have tried other headphones as well (also with a standard audio jack), but the same problem occurs. As I mentioned in my first post I used the command "alsamixer -c0". It gave me output with several "equalizers" where I can adjust the sound volume by using the arrow-keys up and down. But there is no listing for the headphone. Here is a picture of the output.
And before you might wonder, I can also adjust the volume on my headphone, but on other headphones where this is not possible I have the same problem.
I have used a headphone with a microphone as well (for Skype) and the microphone works just fine (but not the headphone). Using Windows XP on the same machine, the headphone works perfect.
Thanks tredegar so far for your time and interest.

I'm using Fedora 12 and there is no file called /etc/modprobe.conf. There is a directory /etc/modprobe.d/ which has the following content: anaconda.conf
I haven't used fedora, and this sort of thing is distro-specific.
Do any of those files have anything about options in them?
I have a file /etc/modprobe.d/options It is owned by root:root and perms are 644
You could try creating that file and putting the module options line from post #6 in it.
But rather than "just geussing" it would be better to find out how F12 manages module options. I have searched around, but cannot find it. Maybe make a post to the LQ Fedora forum "How to set kernel module options in Fedora 12?"
Several people have encountered this problem. In my case I'm running Kubuntu 10.10. Before the latest update, the headphone jack worked; now it doesn't. I have an Asis K60 laptop; apparently the problem is machine-specific. I too see the headphone greyed out in alsamixer.
At this point, I'd try a different headphone, not because I suspect your headphones are bad, but because it's a very easy test and sometimes trouble-shooting easy is more efficient that trouble-shooting most-likely.
