How have you fed audio to it in the past?
There is a wire that runs from the DB-9 to the sound card on the inside
of the node. It is possible that that has come loose or something. All
it is is a bridge from the left channel of the line out to pin 9. There
is a similar bridge between the left channel of the line in and Pin 8.
Do you have one of the fanless cases? If so, you should check the DB9
cable for possible damage as well.
