LINE_OUT and MIC_IN not working simultaneously in andorid 15

[subash_p]

Hi,

I am using an i.MX8MP custom board with the SGTL5000 audio chip. Using TinyPlay, I can able to record and play WAV files from the Android 15 console. However, in the UI, I cannot use the microphone and speaker simultaneously. If I set the device speaker to SGTL5000, the recorder app cannot record (mic_in not detected). But if I disable the device speaker, I can able to record sound using the recorder app.


I will attach my DTS nodes and configuration files below.

sound {

compatible = "fsl,sgtl5000";

model = "sgtl5000";

codec-master;

ssi-controller = <&sai3>;

audio-codec = <&codec>;

audio-routing = 

    "MIC_IN", "Mic Jack",

            "Mic Jack", "Mic Bias",

            "Headphone Jack", "HP_OUT",

            "LINE_IN", "Line In Jack",

            "Line Out Jack", "LINE_OUT";

no-audmux;

};

codec: sgtl5000@a {

compatible = "fsl,sgtl5000";

reg = <0x0a>;

clocks = <&audio_blk_ctrl IMX8MP_CLK_AUDIOMIX_SAI3_MCLK1>;

clock-names = "mclk";

pinctrl-names = "default";

};
