New Encore ENM232-8VIA - No sound

Question

Just installed new Encore ENM232-8VIA sound card. Used Encore supplied CD to do install.. DM says it's working. Drivers installed. BUT got no sound.(Speakers are plugged and on.) Called Encore "Support". Said - no idea why but try reinstalling card to new PCI slot. Did that. Still no sound. Removed hardware and let Windows do it's thing at reboot, but still no sound. Ideas how to fix? I'm a novice.
