I recently put together this system and chose the phillips acoustic edge for my sound card. The system runs great, @1.2 GHz, 512 ram and w/ win98 se. Right now I just have two speakers, and am planning on moving to a 5.1 speaker system later, but whenever I play any sound files, there's a weird crackling noise in the background...has anyone else seen (heard) this problem? Is it the sound card or something else? The crackle is pretty low, but it's definately there...Any suggestions would be appreciated...
