Check what midi and audio input is set to that you are not getting some feedback, but I suppose if you did a factory reset many times.
What default midi output is.
And, you said the onboard sound worked but the front had noise ? the front goes from the motherboard through un shielded wires but if the back port sound was good but one channel.
With RealTek can't you set the port you plug in to what output you want ? speaker/line
