This is Don. I had problems with my computer just recently. Lots of problems w/ registry etc. I would also lose my sound device functioning while logged on the computer. My hard drive finally crashed and I just reinstalled Windows XP. Installed all updates...took hours! lol.....however, now there is no sound coming from my speakers. I checked the device and it is saying that I can not play any media files because the sound device is either missing or not working properly. I tried looking for drivers to correct this problem. Can't seem to get it right. I think the sound device is Legacy. Can anyone help! Please Help!
