I am not able to find the audio driver for a Compac Presario SR 1703wm. This computer had a bad hard drive and the restore is no longer available. I called HP and they wanted to charge me 70.00 for support. There was not a disk with the system. It came from WalMart. I looked on HP's site and was not able to find the audio driver. I found some info that said it was an AC 97 sound card. I tried driverguide.com and installed the c-media version but did not work. Please help.
