recuring "no audio output device is installed"

I have a toshiba satellite U300 laptop, vista home premium 32 service pack 2. About 6 months ago I got the notorious red x through the speakers - I fixed it by re-installing the realtek audio driver. About a week ago the problem re-visted. At first, I uninstalled/reinstalled the driver which brought the speakers back, but everytime I turned the computer on the sound was gone again.I did this at least 8 times in the last week. I did system restore numerous times - to the point that now it doesn't even go back to a point when the audio worked. Now even this doesn't work and no audio device registers under sound in the control panel or sound, game controllers in device manager. I've read the forums on this for hours and tried many things since (including cleaning the disc, defragging etc.) The latest thing I have done is run the system file checker (sfc.exe) and got back several errors which it did not fix - maybe that's my problem?? I have no idea (although I have read the "how to analyze the log file entries) what to do with these results or what to do in general. I still have no sound after spending hours reading and trying to help myself. Can anyone help?

since no one seems interested in answering my question - I will answer it myself:
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

Go into Control Panel\Sound. Are your speakers shown as enabled?

You can also check in the Device Manager to see if there are any yellow triangles next to to the sound selection.

My computer worked fine then I got the red X on the sound Icon.
I had the same issue and tried everything under various advice areas and found this solution that worked to turn back on the sound. All is fine now. None of the other thing worked including updating all the device drivers.

Enter Start then type in regedit in the Run area

Locate the HKEY_LOCAL_MACHINE
Then SYSTEM
Then SERVICES
Then AUDIOSRV

Under here look at the DependonServices

Delete everything but RpcSs and reboot the computer

And low and behold SOUND
