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?
Probably.
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.
Also, it is possible that the sound card/chip is NOT connected to the PC speaker. Most (all?) laptops / notbooks / netbooks / tablets do include speaker(s) connected to the sound card/chip. Most (all?) *desktops* do not -- they require *external* speakers ("sold separately") to be connected.
Since this calls itself a "Mobile Workstation", I am not sure how things are connected. Is "Mobile Workstation" 'fancy' terminology for "laptop" or is it something else? Is this a 'lugable' machine (eg a desktop with a carrying handle and built-in monitor)?
Any assistance or direction would be appreciated.
