No sound on ECS p4m800pro-m(v1.0a)

I got a new pc for christmas, the motherboard is an ECS p4m800pro-m(v1.0a)
It says I have realtek onboard soundcard ac97 codec alc655…via chipset I believe…I installed the latest driver for it and my sound still doesn’t work, everything is connected, all devices are enabled,and the sound is all the way up but it still will not work…any advice would be appreciated.

Go to Control Panel and click on the Sounds and Audio. Check to make sure you audio isn’t muted. Then check all the tabs to see if they show your device correctly.
