I have a Dell Inspiron 8600 laptop, and a couple of weeks ago the speakers stopped working.
I have checked the volume settings and they're fine. In the Device Manager, I can't tell which of the entries would contain the driver for the speakers. Under "Sounds and Audio Devices", everything looks good except for a red circle with a line through it over "Device Volume".
Normally I would delete the driver and restart, but I'm not finding the driver. Any ideas?
