no audio output device installed...

Hi all

I have a hp compaq presario f700 windows vista service pack 2. I have lost sound and have a red x over the speaker sign. Also as i hover the mouse pointer over it; it states that no audio output device is installed.

I went to device manager to see if i could fix it and there is no sound, video or gamecontroller option there.

I went to the hp website to download audio drivers and when i do i get a message stating driver installation failed could not find the device for this driver

I tried using microsoft fix it with no success

I've made sure that audio was enabled and automatic upon start..

Please help don't know what else to do

I've have tried all those drivers and I get this message "driver installation failed: could not find the media device for this driver"
