I'm dense when it comes to this sort of thing so please excuse. Hydro cut power after I made sure machine was unplugged, to replace a power pole. Monitor is an ACER27. Realtek high def speakers (are they inside the monitor?). No sound. Have checked the obvious. Sound is up, cable with green end connected at both ends, drivers up to date. Windows assures me that speakers are working properly when I go to troubleshoot. Unplugged cable and reconnected. Rebooted. Still no sound. Am I missing the obvious?
