Compaq presario v2000 sound drivers

There is a simple sol to ur problem and even i faced it with my laptop as i have the same laptop.
just go on properties of my computer and click hardware on top and then device manager
then right click on the yallow missing audio driver and click on update driver
this will automatically update ur driver from net

if u dont see the update driver button tthen ull have to install service pack 3 first

u can even download realtek AC97 driver and the update as that is more efficient

updating can take 20-30 min so u have to keep patience

u can update other drivers too like this
hope u again listen to the audio from ur com
