LINE_IN and LINE_OUT in sgtl5000 not working in imx6ul target board

[sourabhdas]

Hi All,

We were having imx6 ultralite target board. Audio Codec sgtl5000 is used. MIC_IN and HP is working fine,

But LINE_IN and LINE_OUT is not working. kernel version 4.1.15 is used.

Below are the sound entry in the devicetree file:

sound {
        compatible = "fsl,imx-audio-sgtl5000";
        model = "imx6ul-sgtl5000";
        audio-cpu = <&sai1>;
        audio-codec = <&codec>;
        audio-routing =
            "LINE_IN", "Line In Jack",
            "MIC_IN", "Mic Jack",
            "Mic Jack", "Mic Bias",
            "Headphone Jack", "HP_OUT";
    };

For using LINE_IN for recording purpose, we selected the 'Capture Mux' to 'LINE_IN' and set the 'Capture Volume' values to 12, using amixer. But we are not able to record anything.

Can anyone have got line out port working with sgtl5000?

Or anything i am missing?
