Using the mini jack gives very low volume. Using the RCA and the sound level is high.

I have found the ground wire for my HU, connect it to where I ground my PC casing and the noise goes away but not all of them. I have also noticed that using the ground loop isolator actually decreases the sound level.

The noise is still there although suppressed a lot. How can I reduce it even more? Could it be the grounding of the components in my PC. I have to make sure a good contact for all the components to CPU casing right?

Nomader how do you find out noise is coming from hard disk? I would like to try on mine setup.

Thanks!!
