I have problem on my sound driver can you help ?
I am running Centos 5.4

Not without more information than you have provided. Please do the required reading and learn about how to ask a good question. As a minimum show the results of "/sbin/lspci -m" and describe the exact symptoms. Does a driver load? Any error messages in dmesg or /var/log/messages?

Hello Sir
I did as you said to me and this is the result

Someone with similar issues found kmod_alsa from ELRepo to help.

hello
First, thanks for your time
second, I followed the like you gave me and I installed ELREPO and made sure that the speakers are not muted. and I don't know what to do?? can you provide me with some commands to test the problem ?

Have you installed kmod-alsa and run system-config-soundcard?

kmod-r8168 is not kmod-alsa.

I gave up now, I am so sorry. I installed the package and it is still not working. I will uninstall Centos and go back to windows server. Sorry

I am sorry for giving up. I will try again

I have already installed Kmod-alsa driver and I still have the same problem.

Note: My processor is 64bit but I am running 32bit Centos 5.4

I tried to install the new version of alsa driver and I found this error also. may be this is the problem ?

That did not install the package, just listed the information about it.

Quote:
Source Installs are problematic in general are not recommended except as a last resort. Looks to me like the modules were never built before attempting to install them, and the makefile is not very robust.

Thank you so much for responding rapidly

But from the mentioned information it says that the package already installed. So ???

The errors are from your attempted source install. Perhaps you installed the package, but just did not show it; however, the attempted source install apparently removed files. At this point I'd clean up the mess left by the source install as best you can, remove kmod-alsa, reinstall from ELrepo, and then run system-config-soundcard.

Hello Sir,
i am so sorry but I uninstalled the operating system and Installed new copy of it and I installed kmod-alsa package from elrepo and It is still not working ... any advice ?

We need a bit more to go on than "It is still not working". Please describe what you have done to try to make at work and what error messages you are seeing.

Hello,
my laptop is an HP DV6, too. I've written down what I did, for giving the sound working. It's simple, look here:

centos hp dv6

regards

Thanks for the pointer and for taking the time to document on the Wiki.
