My system is: Asus G51VX-X3A Laptop Realtek HD Audio w/ latest drivers Windows 7 Home A few days ago, I noticed that the speakers on my laptop were no longer working. I could plug in headphones and the headphones still worked. After searching in other forums, others suggested the headphone jack being stuck in thinking it was in headphone mode instead of switching back to speakers. So, I got a flashlight, a pin and tinkered with it but with no fix. Last night, I cleaned out all the old drivers and reinstalled the latest Realtek drivers with nothing. I remembered the laptop has an explosion sound that plays at POST, so I re-enabled the sound in the BIOS, rebooted and it the sound played. I had it narrowed down to a software issue. Someone has just suggested a registry edit to me that I tried: I gave it a shot, rebooted, and voila, speakers worked in Windows. I plugged in headphones, and nothing. I wasn't expecting a magic fix, but I got closer. This is where I'm stumped. Any ideas where to go from here?
