This happened only once about 6 months ago and I uninstalled/installed the realtek audio driver, and there was peace. However, in the last two weeks this problem revisited and got much much worse. At first a system restore took care of the problem ( I even tried to stop the windows updates - although it seems to be updating anyway??). I have uninstalled and reinstalled the driver at least 8 times in the last few days. Now everytime I turn on the computer it comes back on with the red x through the speaker. Restore is now useless as I can't go back far enough. There is no trace of any device in "sound" nor is there anything like a sound or game controller in the device manager. However, the driver does show up in the control panel??? So, I uninstall, reboot, install the driver and reboot. The speakers work. Next time I turn on the computer the x is back and no sound. I have a satellite vista 32.please help thnx1 person needs an answerI do too

I have a satellite U300 vista 32 service pack2. I have uninstalled/installed the realtek audio driver at least 8 times this past week. The speakers would come back but the next time I turn on the laptop the speakers are gone again. I have also done numerous system restores which no longer do anything since they don't go back far enough - now I have no sound and can't get it back up. I have done disk cleanup, defrag and checked for viruses (none found).

thank you Gokul,I don't have a Vista DVD -it occurred to me maybe i don't have service pack 2 but when i go to my system properties it clearly states windows vista home premium service pack 2????? (Is that what made you assume I should have a DVD?)

After spending many many hours on forums and support sites and trying all kinds of things (most of which were incredibly complicated techie remedies) I found nothing which helped me but thousands of other windows people with the same problem or a variation thereof. Until, by some miracle, I found a simple suggestion on yahoo answers: "...go into the control panel/Users and turn off user account control. After I did that the driver installation was successful..." and voila after more than a week of silence I have sound!! Worth trying oh yeah - that was too good to be true - worked for two days and the sound is poof gone againany ideas out there ( I don't have the vista DVD)??
