I have installed Fedora 8 on my Laptop. I do use head phones. At first I don't have any problem, but suddenly sound is coming out of my box though I connected head phone. The problem is solved sometimes when I reset audio configuration files and reload audio drivers. But it is not working every time. I have to listen to the lectures in the class, so it is very difficult for me. Please give the instructions what to do?

When I have no problem, I can find one extra option (Master) in Volume Control. If I have the problem that is not visible.

Here is the drivers details.

Vendor: Intel Corporation
Model: 82801H (ICH8 Family) HD Audio Controller
Module: snd-hda-intel
PCM device: ALC268 Analog
ALSA Driver Version: Driver Version 1.0.15
ALSA Lib pacakge(s): alsa-lib-1.0.16-3.fc8
ALSA Utils package(s): alsa-utils-1.0.16-3.fc8

I observed one more thing regarding version. If the version is 1.0.16 then it if working properly if it is 1.0.15 gives the problem. How to update this driver to 1.0.16 version. (I think this may be the problem).

Any help would be appreciated.

Thanks in advance

Sounds like you have a simple audio socket or plug problem.

I once had much the same, turned out the problem was the audio jack was getting worn out, sometimes the headphones would have sound, but the slightest movement of my head would switch output to the speakers. Turns out the headphones weren't making contact well enough, switching the audio output to speakers and headphones intermittently. Physically holding onto the plug and constantly forcing it into the socket was all that worked. Releasing it to stay plugged in by itself merely had sound jumping between headphones and speakers intermittently.

I doubt that you have a software or driver issue.

thanks...
I do think same. But how can I update my driver from 1.0.15 to 1.0.16? Is there any command like yum update alsa or do i have to download rpm?
thanks in advance
