Hello. Thank you for taking time to reading my Topic about this. I have been facing this problem for some time. I asked for tech support with the HP CHAT feature. nothing helps. this is what the problem is. Each time I Restart my computer (or at random times) the drivers for my sound card remove them self from my hardrive.I have to reinstall them each time. and cant hear any sound from the speakers. in that case I also cant hear sound from ONE of the .avi formats for final FANTASY 7 ADVENT children. due to this problem. How I know its the problem: I use winamp for .avi formats. and when theres no sound drivers avilable the winamp program says "No mixers avilable cannot play video" or whatever somthing LIKE that, anyway when running FF7AC the video plays with out any sound. its annoying to reinstall the drivers each time this happens and I faced this problem since March of this year.

Computer Info:
2.66Ghz Intel Pentium 4 Processor
512MB DDR1 RAM
Sound Card: Realtek AC'97 Audio.
Is anyone else experencing this problem? or has anyone had it before?You may need to update your sound drivers.
