Can you measure the action on that string.... Both 1st and 12th fret...... A little too low and the string just kinda goes dead. It's weird - but you don't really get rattle..... It just doesn't sound out.
Can you try shimming up the saddle with a slice or 2 of plastic peanut can lid (milk jug, whatever). The test is to raise the string 0.010 or 0.020" and see what happens.
