Over the last few weeks, after booting the computer, the speaker icon would display with a red "X". Sometimes the "X" would clear itself and sound could be heard, other times it didn't clear and rebooting was often helpful. Now, the red "X"is there constantly and I cannot get any sound.
I have downloaded and installed the Realtek HD Audio Driver but that hasn't helped. The sound icon displays, "No audio Device is Installed" message. The Sound Control Panel shows no devices installed.
Where would I look to make sure the driver installed properly?
