I won't comment that it isn't exactly smart to do so, because you admitted that already.
- If the cd that you don't have is a Windows CD indeed, it won't contain the driver. If it's a socalled 'restore CD' using it will bring the computer back in the state it was in when it left the factory, although some of those restore CD's are somewhat more sophisticated. Anyway, I don't know any details of what you don't have.
- If the OS is Windows XP, you can try System Restore back to when it worked.
- Maybe the computer came with a sound driver CD (with drivers and music programs and the like) or a simple sound driver diskette? Have a look around.
- Your best bet maybe should be to go the sony support website and search for the drivers for your model of the Vaio. Vaio's aren't custom made, so there's a fair chance you'll find the right one. That's the first thing I would do.
Hope this helps.
I recently deleated my sound driver (I Know i'm an idiot) on my Sony Vaio PCG-TR1A and my sound doesn't work. I think the driver was a version of SoundMax and I have tried downloading drivers off of their site, but nothing works. My question is: Do I need to reload the windows xp cd that came with the computer to get soundmax back? If so, I do not have that cd. What options do I have if I cannot find the cd?
