...the sound card and the wireless card.. Updated software will frequently fix such issues.
Hope this helps.
I had recently had to relocate my system and in doing so I had to add wireless PCI card. When I'm connected to the network anytime a sound is made or listen to a song, etc the sound sounds like when you slow down a record player. I'm running XP on an AMD 3200, 1gb RAM an SB audigy 2ZS sound card on a EVGA motherboard and D-Link extreme router and wireless card. I have also used the onboard sound and get the same problem. I don't understand how the wireless card can affect the sound. Any help would be greatful.
