Hello - I hoping someone else has experienced this problem before with upgrading from the factory installed W' XP Home to Professional on a Compay Presario, Pentium 4 PC.
About a year and 1/2 ago, I purchased the Compaq which came loaded with W' XP Home. I upgraded it to XP Pro SP1. At some point, I noticed I had lost sound capability, Windows sound, CD and video sound. Not sure if it was simultaneous with the upgrade since I was too busy using the PC for other things to bother with fixing it when it was first noticed.
However, I began trying to fix it this week, using the Windows Troubleshooter to no avail. I also called Microsoft who couldn't help and referred me to HP/Compaq. HP indicated they couldn't help because they don't support any of their PC's if the OS has been changed! Further, the HP rep indicated that the only way I could get sound back was to revert to XP Home as the sound card is located on the motherboard and it just won't work with XP Pro (what a bunch of BS).
The sound card is a RealTek AC'97 and I deleted the driver and downloaded the latest driver from the RealTek web site. No change. The Device Manager indicates that the driver is installed and working properly, however, it also indicates that there are no playback devices, no recording devices and no MIDI devices.
Anyone had a similar problem?
Thanks.
