Jumpers on the SNAC Board

Hello,
The SNAC board has two jumpers. What are they for? When do you plug them in and when do you not? I cannot find any documentation on this.

Correct me if I am wrong…
The Connector X1 has Pins for the Low-Level Input Signals LV7 and LV8.
I have no Idea what the reason for this Connector is.
Maybe to have a bypass input possibiliy?
The „Jumper“ connects the USB-Side Input Pin 9 (TX+) to the Input Signal LV7.
What is Pin 9 on MiSTer IO Board Side?
I think it Is the Jumper for 3.3V/IO to IO6 ?
The „Jumper“ on the SNAC Board should be closed or some SNAC connected devices don‘t work correctly.
As I don‘t find these Jumpers on the Mini Versions of the SNAC boards it looks like they are History now.
