Hi, I'm quite frustrated considering I have tried everything, and nothing seems to work. My friend recently gave me a computer from his work, and the computer was reformatted, and I can't seem to get the sound working. I have tried various speakers/headsets, and checked the volumn to see if it is muted, and everything is functioning properly. I checked the sound driver, in the device manager, under " Sound, Video, and Game controller," and there is a driver installed, Realtek, that is functioning without any problems, no conflicts, enabled, and has a signature. I pressed "update," and the updates always say I have the latest version. I also have a Powerspec B600 computer, with Windows XP, went to thier website to find if my driver is compatiable with my computer, and I have the Realtek audio 5. something version that they have suggested for my computer, so its the correct driver for my computer..However.. I then installed the latest version from the Realtek audio website, and still the same problem. I have done all the troubleshooters..and nothing, everything seems to be functioning properly. The only wierd thing is when I check device manager, under "system devices," there is an option for "system speaker" which says no driver is installed, yet under "Sound, Video, and Game controller" it says a realtek sound driver is installed (and it's the default for playback) So, at this point, I just don't know what else to do, and how to locate the problem. PLEASE HELP!! It's driving me crazy to live without sound, and i'm very desperate to find a solution..
