Hi to all,
as all of you, I have the same problem... My computer refuses to output sound...
I have c-media ac97 onboard audio device (on Windows XP sp2), and everything was
fine until few days ago (I don't know what happened!!!).
It seems like the audio device is fine but I get the "driver is enabled but has not
been started" message (when I go to the properties of the audio device).
I have also noticed that the Plug and Play Software Device Enumerator has this irritating
exclamation mark next to it (the error is: "This device is not working properly because
Windows cannot load the drivers required for this device. (Code 31)").
I've tried all the suggestions on this thread and I still can't get rid of the error.
I've also tried to uninstall/reinstall the audio device...Nothing helps!!!
When I'm trying to delete some of the registry keys (Ven's suggestion) I get this
error: "cannot delete swenum. Error while deleting key" although I gave myself permissions.
One more thing: I have two HD and on each one of them I have Windows XP (I'm not
sure if the other one has sp2 - It's my backup drive) and everything works perfectly
when I boot from the backup drive - So I'm sure this is a software problem!!!!
I'm totally helpless!! Somebody please help me...
thanks in advance,
Alex.
