I have an HP pavilion dv6748us laptop. Now my problem is Windows made some automatic updates just the other day and once those updates took I now have no sound on my laptop. My audio icon has a red X next to it which states "No audio output device is installed when the cursor is placed over it. I googled the error message which suggest that I go into device manager and update the drivers. I tried that and no change. I did a search on my computer for sound and clicked on the audio icon and it read no audio device installed. I went to HP support site and downloaded all three of the audio drivers for my model of computer, still nothing. I went to the microsoft website and ran the audio diagnostic test and it could not resolve the problem. Now I don't know what else to do. I need help it is beyond my limited knowledge on this issue. By the way I'm running windows vista on this computer. Thanks in advance for any help given.
