Rockchip Android13 AudioCodecs ES8316 debugging experience

Debugging audio is divided into software debugging and driver debugging.

When verifying the output of the Andorid13 audio headset, using the apk to play an audio, it was found that only the right headset has output and the left headset has no sound. According to debugging experience, it is generally a driver problem.

First try tinyplay to play headphones. To use tinyplay, you need to switch tinymix to the headphone channel first:

41      BOOL    1       Right Headphone Mixer Right DAC Switch   Off

Find the audio hal layer code codec config, hardware/rockchip/audio/tinyalsa_hal/codec_config. Switch the headphone output description in es8316_config.h:

const struct config_control es8316_headphone_normal_controls[] = {
    {
        .ctl_name = "DAC Playback Volume",
        .int_val = {192, 192},
    },
    {
        .ctl_name = "Left Headphone Mixer Left DAC Switch",
        .int_val = {on},
    },
    {
        .ctl_name = "Right Headphone Mixer Right DAC Switch",
    .int_val = {on},
    },
};

Then use tinymix to switch to the headphone channel according to the above configuration:

tinymix 4 192 192
tinymix 39 1
tinymix 41 1

Then use tinyplay to play the es8316 sound card and test the headphone output:

tinyplay data/48000_2channel.wav -D 0 -d 0 -n 3 -p 480

At this time, when I heard the earphones, only the right earphone had output, after confirming that there was no problem with the earphones. Confirm that the codec is normal when comparing Android 12, and compare the codec registers during playback of the two versions.

/d/regmap/7-0010 # cat registers // es8316挂在到i2c7总线上

The comparison registers are different as follows:

Compare the difference register values and modify the codec code to the configuration register.

 }

After modification, the register configurations during playback of the two versions of codec are consistent. I found that there is still a problem with the headphone output in Android 13. I suspect it's a board problem. Just replace it with another board and it will be fine.

If it is a Linux version, use the alsa utils tool amixer to switch routes:

Amixer is modified as follows:

amixer -c 0 cset numid=42 1

amixer -c 0 cset numid=31 1

3588 linux codec register command:

cat /sys/kernel/debug/regmap/7-0010/registers

After the registers are consistent, there is still no sound. Compared with Linux, refer to dts: rk3588-evb3-lp5.dtsi:

&i2c7 {
    status = "okay";
    es8316: es8316@10 {
        status = "okay";
        #sound-dai-cells = <0>;
        compatible = "everest,es8316";
        reg = <0x10>;
        clocks = <&mclkout_i2s0>; //linux版本
        clock-names = "mclk";
        assigned-clocks = <&mclkout_i2s0>;
        assigned-clock-rates = <12288000>;
        pinctrl-names = "default";
        pinctrl-0 = <&i2s0_mclk>;
    };
};

And the android version:

es8316: es8316@10 {
        status = "okay";
        #sound-dai-cells = <0>;
        compatible = "everest,es8316";
        reg = <0x10>;
        clocks = <&cru I2S0_8CH_MCLKOUT>; // android版本
        clock-names = "mclk";
        assigned-clocks = <&cru I2S0_8CH_MCLKOUT>;
        assigned-clock-rates = <12288000>;
        pinctrl-names = "default";
        pinctrl-0 = <&i2s0_mclk>;
 };

After modification, aplay now has sound.
