The relevant ones have long since been overwritten. I tried a restore point when it first happened, and that didn't help. I don't recall installing anything interesting (or anything at all, actually) right before it happened, except for a MS automatic update. Nothing else in Windows is behaving oddly. The sound card is not turned off in the BIOS, in fact there is no place in the BIOS to do that. Says there are no input or output devices present. The Sound panel in Control Panel is checked off to show disabled/disconnected devices. The device drivers are all up to date and none of them show a problem. the proper Services start up and are running. The Windows sound troubleshooter can't figure out the problem - i.e. Everything worked fine for a while, then one day the volume indicator in the task bar had a big red X over it, and claimed I had no audio devices installed. It came with Win8 pre-installed and I applied the free upgrade to Win 8.1. I have an ASUS X75A laptop, with built-in sound card (a proprietary VIA model that ASUS uses it shows up as a "dev8446").
