Okay - here is this weekend's deal: I am working on my dad's computer (again) and now what has happened is that it has lost all sound functions: system sounds, third party programs, pings, squeeks, etc. -- all vanished. I did the following to no avail:
Virus stuff -- none found.
Device Manager - says it cannot find a program to update the driver on some hardware I don't think is really there anyway.
Restore -- nope.
Repair and then a fresh reload of Windows XP Pro Service Pack 2 with updates (three times).
Delete all software associated with ATI All-in-Blunder 9000 and all Sound, Video and Game Controllers; remove devices from Device Manager and allow XP to "find" them on reload -- Normal mode and Safe mode.
Physically remove ATI card and rebooted w/o it; then "installed" it as new. No go.
Downloaded numerous Registry-fixer programs.
Physically checked the solder contacts on the basic on-motherboard sound components. Look fine.
Device Manager has "Other Devices" it finds someplace in my hardware -- "Multimedia Audio Controller" which it does not recognize as being manufactuered by anyone and is unable to find any software that it might like to use; and Video Controller (VGA compatible). No driver updates for either, of course, and when these alleged "devices" are "removed" nothing changes -- they are found upon reboot -- yes, in safe mode as well.
Last but not least, I went online and searched for other people, similarly situated, and found numerous blogs and message boards complaining of the identical thing. I followed each thread to the bitter end and I have yet to find anyone who solved their problem. All are XP Pro with recent updates, as am I. Computers included Dell, HP, Compac, etc. Some used ATI cards; some did not.
Any suggestions anyone?
