Hey everyone...I just would like to know if its possible to use a PCI sound card and Onboard sound simultaniously because i use dj programs that require me to cue up songs in my headphones before i mix them up on my stereo system, but when i plug in my headphones to the PCI sound card and my stereo system to the onboard sound (or vice versa), the sound completely stops and all i hear is some scratchy noises, but no sound. My board is a MSI KT-6 Delta with AC'97 onboard sound (C-Media) and i have a generic PCI sound card. thanks.
