No audio output

[11172]

I've spent two days on message boards and trying to dowload drivers.  I also read through all of these threads but don't see a solution that works.  My computer was off for the weekend, when I turned it back on I get the "No Audio Output Device is installed".  Yes I realize there are severals posts on here about this, but not provide the right solution.  When trying to uninstall the Codex driver, nothing happens.  It stays in programs.  When trying to install other drivers I get "Driver Installation failed; could not find media device" or "could not find device for this driver".  No help from HP without $100 charge.  Bought to HP's since 2007.  This is dv6636nr with windows vista.  Tried going back and restoring to last week, didn't help.  Can't unistall, can't install, don't have sound....except when a window pops up and a large BEEEP happens.  Can't adjust volume on the keyboard and have the red X over the speaker in the bottom right.  Help.

Download and install these drivers in order:

BIOS

Chipset

Audio

Do I need to try and unistall anything?

Uninstall OLD audio and chipset drivers..

restart your PC then install these drivers and then restart

The BIOS download at least got rid of the speaker with the red X.  On to the next download, thanks...hope it helps.  What did BIOS change do?

Already downloaded the Nvdia but haven't restarted my computer.  Your thoughts before moving ahead?

Checking programs I see Conexant is still there, but I have not used the unistaller pro yet; shall I proceed?

[Pankay]
