After getting my Asus desktop back on after 80 days in storage because of my house fire, I now can't get any sound coming from speakers, but not sure I have connections correct.

I have an on board Sound Max that my Audio is set to use in my Control Panel.
I installed a M Audio Delta--Audiophile 2496 when I built the computer. However, I don't recall connecting to it for sound. I haven't installed the connector with 2 large and 2 small black ends.
My Audiophile 2496 doesn't appear to be working when I click the icon I get dpInitinterface failed
Here is what I connected:
red-white out of computer over to my subwoofer (attached to a green ended plug) on my controller of the subwoofer and 2 speakers behind my Roland FP-4 digital keyboard.

What to do for sound?
