Hi, I'm currently running a Samsung NP305E5A-A03US laptop with Windows XP. After some intense searching I managed to find all the drivers for it (the Samsung website only has Win7 drivers). The last driver I found was for the Realtek HD Audio. Immediately after the audio driver was installed the sound started working. I was getting Windows sounds as well as music. I rebooted the system so Windows could install an update (I don't know which update), and when the desktop came back up, the sound wasn't working again. According to control panel everything, is working fine. I even tried uninstalling/reinstalling the driver again, but nothing works. Any help on this would be appreciated. Thanks.
