[yanis]

Hello,


product name: hp pavilion dv2500

model number: dv2710us

windows 7 ulttimate 64 bit



my hp keeps telling that have no audio output device installed and theres the the image for volume with a large red circle with a white x in it.



this is not true because i have contexant (i think that's what it is called) speakers installed.



Lately when i would restart my computer the sound would work intermittently but for the past two days whether i restart my computer or not the image for volume with a large red circle with a white x in it is still there and says no audio output device installed. PLEASE HELP!

try installing the drivers again:

the 64 bit vista ought to work

also make sure it is enabled in:
Control Panel\All Control Panel Items\Sound

you may need to right click - enable "show disabled" and "disconnected devices" to see everything
