Rockchip Android13 AudioCodecs ES8316调试心得

调试音频分为软件调试和驱动调试。

验证Andorid13 音频耳机输出的时候，用apk播放一个音频，发现耳机只有右耳机有输出，左耳机没有声音。根据调试经验，一般来说是驱动问题。

1. 先试用tinyplay播放耳机，使用tinyplay，需要先tinymix切换到耳机通路：

38      BOOL    1       Left Headphone Mixer LLIN Switch         Off
39      BOOL    1       Left Headphone Mixer Left DAC Switch     Off
40      BOOL    1       Right Headphone Mixer RLIN Switch        Off
41      BOOL    1       Right Headphone Mixer Right DAC Switch   Off

查找音频hal层代码codec config, hardware/rockchip/audio/tinyalsa_hal/codec_config. 在es8316_config.h中切换耳机输出描述：

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},
    },
};

然后根据上述配置使用tinymix切换到耳机通路：

tinymix 4 192 192
tinymix 39 1
tinymix 41 1

然后使用tinyplay播放es8316声卡，测试耳机输出：

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

这时候听到耳机也是只有右耳机有输出，在确认耳机没问题的情况下。确认对比android 12的时候codec是正常的，对比两个版本的播放时的codec寄存器。

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

对比寄存器如下不同：

对比差寄存器值，修改codec代码对配置寄存器。

     return 0;
 }

修改后，两个版本codec播放时的寄存器配置一致。发现android 13还是耳机输出有问题。怀疑是板子问题了，换了一块板子烧写就好了。

如果是Linux版本使用alsa utils工具amixer切换route:

对比上面tinymix主要修改ctl如下：

numid=5,iface=MIXER,name='DAC Playback Volume'
  ; type=INTEGER,access=rw---R--,values=2,min=0,max=192,step=0
  : values=152,152

  : values=off
......
numid=42,iface=MIXER,name='Right Headphone Mixer Right DAC Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=off

amixer修改如下：

amixer -c 0 contents
amixer -c 0 cset numid=5 192 192
amixer -c 0 cset numid=40 1
amixer -c 0 cset numid=42 1
amixer -c 0 cset numid=2 3
amixer -c 0 cset numid=31 1

3588 linux的codec寄存器命令：

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

寄存器一致后，还是无声，对比linux 参考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>;
    };
};

而android版本：

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>;
 };

修改后，aplay播放有声音了。

aplay -D hw:0,0 sdcard/48000_2channel.wav
