Logitech 5300e: How to get rid of the echo?

Im using logitech 5300e with the on board audio that came with my nforce 3 mb, which is Realtek ALC850 8-Channel Codec. I have been playing with the settings some and nothing seems to work.

yup, my friend had exactly the same problem and i fixed it for him. You need to install the correct drivers for the sound. My friends computer was using windows sound driver and they put on that echo, just install the correct drivers.
