Reply to Onboard sound - VCI doesn't want to know Traktor

Hi all. Had a bloody evening mare with this toevening . Just got a VCI and seem to have an issue with my onboard sound. I am ordering the audio 2 soundcard over the next few days, but for the next week or so i'd still like to use the VCI and get some practice in. I have the 1.3 firmware and Traktor Pro 1.2.1 installed. I've imported the 2.5 tsi mapping off here. Did all this exactly the same on my laptop and that was fine, but the PC doesn't want to know so i'm putting it down to the onboard sound. I've played with all the settings and still no luck. MIDI light just doesnt light up when i do anything on the VCI. It's Realtec HD Audio. Tried updating the driver through device manager and no change. Please help!
