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. I ran "yum update" until all updates were completed, rebooted system because the Kernel changed. The system now works -- all of the following appear to function properly: - USB connections - wireless - ethernet - pointer-stick for the mouse - the display at its "natural" resolution (1920x1200) - An occassional beep does occur, proving that the PC speaker is connected. However, I when I play any sound or movie file, I get no sound. I know that the PC speaker produces low quality sound, but there should be something. I have experimented with the "Sound" setup, but none of the options seem to produce good results. Is there some special driver or option I need? Any assistance or direction would be appreciated. David

Do a 'lspci | grep -i audio' in a terminal window and post the results here. This will list what sort of sound chipset your system has. You may need to download and install a driver, probably from the Elrepo repositority, much like you did for the wireless.> > Any assistance or direction would be appreciated. > > David > > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > >-- Robert Heller -- 978-544-6933 / heller at deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments

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).
