I have a friend who has a Compaq computer with an integrated sound card. All of a sudden he was having problems with the sound. If he played a music CD, the music was "garbled' - kind of like skipping parts of the song. Some of his email with sound would play OK and others would be garbled. The normal WINDOW sounds were "shaky" or "garbled". Then the system simply stopped any sounds. I helped him disable the integrated sound card and installed a PCI sound card. All we got was static (at best). So removed the PCI card, re-enable the integrated sound card. Tried again to produce sound - no luck. At this point, I was thinking there was a problem with the motherboard. A few hours later, he called and said he received an email with a song in the background and it played just fine. But could not get sound from anything or where else. He is running WIN 98 SE. Any ideas????
