You wouldn't happen to be using Boston Accoustics woud you? On the older ones, and maybe some newer, you had a problem with an internal fuse in the sub woofer. Everything seemed fine, power on the speakers, drivers are fine, etc., you had to unplug it for about 1/2 hour (it was a delayed set fuse that was very tempramental). I've had to do this before. Also, another thing to keep in mind. When checking system properties, do this in safe mode. You will sometimes see ghost hardware (multiple instances of the same hardware that show up in safe mode but not in normal). Check in safe mode, then. One thing to try is the following (yes, it requires a reinstall of the sound card driver after doing the following steps):
1. In services, check that WinAudio service is enabled, set to automatic, and running.
2. In Device Manager, System Devices check that Plug and Play Software Device Enumerator is installed and running
If not , then you need to reinstall it:
1. Copy machine.inf from %windir%\inf to your desktop
2. Remove line ExcludeFromSelect=*
3. Use Add new hardware wizard using the Have Disk option
4. Select the machine.inf you saved on the desktop
5. Install Plug and Play Software Device
Uninstall the sound card from DM and then scan for hardware changes. Also check event viewer and see if any errors are there and report them.
If you argue with an idiot he will drag you down to his level and beat you with experience.
