We have a Toshiba Satellite laptop with Windows 7 that no longer plays any sound. We have tried going back to a save point, but that doesn't fix anything. We tried to reinstall/upgrade the driver, but end up with a very long list of devices and we have no idea which one is in the laptop. No audo device shows up in the device manager. When we tried the troubleshooter, we get a message that there is no audio device.
I don't know when exactly this happened, so I don't know if it was related to some installation. We did have another problem with the laptop. It wouldn't start up, except in safe mode. We had to disable start up stuff (I don't remember exactly what we did). I only mention this in case it's an indication that there was some funky virus that caused both problems. We did a virus scan with Kaspersky and took care of any viruses. But the sound problem remains.
Any suggestions on what we might try?
