I am trying to install new Creative Inspire 4.1 speakers on a Biostar M7VKB motherboard with onboard sound. I am not sure if anyone is familiar with this motherboard but I am only able to get two speakers to work at a time. It seems to be a problem with the motherboard because out of the subwoofer come two wires. One for the fron speakers and one for the back. Either one of these will work if plugged into the top outlet of the onboard sound. But neither will work when plugged into the bottum outlet on the onboard sound. I am the latest drivers and latest bios and I can not seem to get this to work. If anyone has any ideas please let me know.
