I'm not sure if the issue with the NEW case or the NEW mainboard.
1. Anyone has an idea on whats causing this issue?
2. Is the front panel audio (from the audio plugs to the header) is just a wire extension, or it has some electronic components? I mean can I just multimeter it for a short or a cut, or it is more complicated?
I'm going to venture here that is is a problem at the front panel in the connections - I've never seen any extra filters or components within the audio connectors which are simply jacks so checking continuity with a multi-meter would be my first step. Keep in mind that the cable should also be suspect. It should be a realtively easy fix - hopefully.
Hope it helps
