Line_out Disable.
Disables the Line_out pins (L/R), placing them into High-Z mode so that the assigned output audio jack can be shared for Line Input function.

0 = Line_out pins have normal audio drive capability (reset default).
1 = Line_out pins are placed into High-Z mode.

linout is disabled if it is a real ad1980
as your emulauted ad1980 does not has headphone out
