I have a T510 using the Contexant 20585 SmartAudio HD driver for the internal speakers. Today they just stopped working. I run the tests and I get no sound left or right. Now I did notice something odd. I open Control Panel and then I click SmartAudio. I then click the third icon from the left at the bottom of the screen (Audio Director). Now on the right hand panel of the screen I see a large, red 'X' beside the laptop. That would be between the laptop and the headphones.... anybody know what that is? (Would it appear to signify that something is amiss with the speaker?)
Anyway, I've uninstalled, installed the latest drivers (May 2010). Still nothing... any ideas?
