JTo switch the TPA0103 amplifier module between center channel speaker and stereo headphone modes using the control signal from the platform headphone jack, jumper JP6 to MODE
JFor center channel only or 3-channel output modes (as selected by EVM jumper S2) leave JP6 open.
3.3.4.3Mute/Mode Polarity Select (JP8)
A second 3-pin jumper header (JP8) on the platform selects the control signal polarity by connecting either the active-high or the active-low line from the headphone jack to jumper JP6.
