1. speaker icon with red cross: mouseover; the audio service is not running
2. control panel/hardware&sound/sound: mouseclick: audio service is not running - enable windows audio service? YES!
3. Sound Tab pops up: Playback/Recording both state "No audio devices are installed".
4. Device Manager: Sound, video and game controllers:
Creative SB Audigy 4 (WDM) - (though it's actually and Audigy 2 and, yes, I have tried numerous other/correct drivers.
PnP Audio Device
SB X-Fi Surround 5.1 Pro (for good measure via usb to test)
Manager states all are working and up to date...
Granted it's an old machine...
What i did to solve this issue was, download the audio driver from the manufacturer site ( not windows 8 driver yet, but i used the one for windows seven/vista) and the went to device manager and update manually the driver. NOTE: windows legend was " last driver is the best one "
So update manually and i hope you fix it. Regards!!!
