Dear Experts

I have been unsuccessful getting the sound to work on a HP Mobile Workstation HP 8540w.

Here's a brief rundown of where I am

I did a clean new install of Centos 5.6 from DVD, using the Gnome Desktop option and no optional modules. I enabled the firewall, but disabled SELINUX.

I installed three files from elrepo to make the wireless adaptor work, and specified the video adaptor using the Gnome -> System -> Preferences -> Display panel.

Hi David,

If you're already familiar with elrepo then I'd suggest you try their updated alsa sound drivers.

yum --enanlerepo=elrepo install kmod-alsa

and reboot.

Also, don't forget to check your sound device isn't muted. The ALSA docs state:

Note: All mixer channels are muted by default. You must use a native or OSS mixer program to unmute appropriate channels (for example a mixer from the alsa-utils package).
