I went to the compaq website and found that the compaq 700 series are notebooks, is this correct?

I take it it's an onboard soundcard then, correct? Often, 2000/XP drivers are the same for sound cards, etc.

The VIA site http://www.viaarena.com/?PageID=2 has the newest Hyperion drivers (formerly known as 4-in-1). These are probably much newer than your Compaq drivers and are dated 5/20/03. VIA drivers are universal, and will work fine with your KN133 chipset. The sound system is AC '97, in other words, integrated into the chipset. They also have support forums.

Let us know if this helps. You could also try a Knoppix CD as a cross-check...

You might find it on drivergide.com its free to join.

knoppix is cd linux...why is this a cross check?

I own one of these laptops and one of the things I did was called Compaq and ordered the set of 3 "Quick Restore" CD's. It was probably one of the best things I could ever have done for this machine. You can still order these from Compaq even if your machine is out of warranty. There are three CD's that have you install the OS in a sucession. 1, then 2,then 3. It doesn't take a long time to do it either. This will restore the Computer back to factory default settings like it was out of the box and all of the drivers for everything will be loaded.
