Note: To have the Line-out connector on the back panel work
properly, you need to place the jumper on the pin# 13~16 of the
JAUD2 connector. Otherwise, this Line-out connector will not
function and nothing can be heard through speakers or headphones
attached to the connector. But MSI front panel audio connector is
enabled at this time and allows you to connect speakers or
headphones.
