I upgraded to a new computer. I used my Audigy 5.1 card. I used the CD that came with the card. Started having spontaneous restarts. Each time XP Pro would prepare an error report for transmission. Finally IE popped up and there was a link to Creative with the software upgrades. I accepted them all, they download and I install each one of them. Following the upgrade my 5.1 sound ceased. 2 speakers will work. All the cabling to the 5.1 speaker system is correct and I have enabled cmss. Any suggestions?
