路由没有完全通。但是其它部分已经完全正常工作了，你在alsamixer肯定能看到注册的声卡。你是不是用的原版内核里的rt5659.c，我传的那份ucm conf是根据我从小米官方源码改来的rt5659.c来配置通路由的，所以直接用那份无法完全连通音频路由。
完全连通的话，tfa989x里面的这些widget全部都会在路由path里的，连通至OUT这个widget即最终喇叭输出。
static const struct snd_soc_dapm_route tfa989x_dapm_routes[] = {
{"OUT", NULL, "AMPE"},
{"AMPE", NULL, "POWER"},
{"AMPE", NULL, "Amp Input"},
{"Amp Input", "Left", "AIFINL"},
{"Amp Input", "Right", "AIFINR"},
};
好家伙你这是替官方做了一版for you
对比小米官方rt5659.c默认连通的路由，发现原版内核默认连通的音频widget路由里IF3 ADC Mux是连通的，但IF2 ADC Mux却没有连通。
{ "IF2 ADC Mux", "IF_ADC1", "IF_ADC1" },
{ "IF2 ADC Mux", "IF_ADC2", "IF_ADC2" },
{ "IF2 ADC Mux", "IF_ADC3", "IF_ADC3" },
{ "IF2 ADC Mux", "DAC_REF", "DAC_REF" },

{ "IF3 ADC Mux", "DAC_REF", "DAC_REF" },
{ "IF3 ADC", NULL, "IF3 ADC Mux"},
{ "IF3 ADC", NULL, "I2S3" },

感谢指点，现在是系统设置里能看到设备。但是扬声器声音很小, alsamixer调adc1为1%就好了，现在是1%声音还是很大
codec_out0 Gain 0 和 DAC1 Playback共同决定音量，可以组合式调一下。
这里初始值我设置为6是比较小音量的。
cset "name='codec_out0 Gain 0 Volume' 6"
cset "name='DAC1 Playback Volume' 6"
百分比设置可能没法太精准控制，建议使用数量设置。命令行可以直接用 amixer cset xxxxxxxx
奇怪，重启之后设置里就看不见设备了。cat /proc/asound/cards还能看见。我这有点玄学
也有可能是一些默认连通的路由干扰的问题，比较大可能是TDM Data Mux这个widget的值影响。
{ "TDM Data Mux", "AD1:AD2:DAC:NUL", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD1:AD2:NUL:DAC", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD1:DAC:AD2:NUL", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD1:DAC:NUL:AD2", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD1:NUL:DAC:AD2", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD1:NUL:AD2:DAC", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD2:AD1:DAC:NUL", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD2:AD1:NUL:DAC", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD2:DAC:AD1:NUL", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD2:DAC:NUL:AD1", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD2:NUL:DAC:AD1", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "AD1:NUL:AD1:DAC", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "DAC:AD1:AD2:NUL", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "DAC:AD1:NUL:AD2", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "DAC:AD2:AD1:NUL", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "DAC:AD2:NUL:AD1", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "DAC:NUL:DAC:AD2", "TDM AD2:DAC" },
{ "TDM Data Mux", "DAC:NUL:AD2:DAC", "TDM AD2:DAC" },
{ "TDM Data Mux", "NUL:AD1:AD2:DAC", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "NUL:AD1:DAC:AD2", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "NUL:AD2:AD1:DAC", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "NUL:AD2:DAC:AD1", "TDM AD1:AD2:DAC" },
{ "TDM Data Mux", "NUL:DAC:DAC:AD2", "TDM AD2:DAC" },
{ "TDM Data Mux", "NUL:DAC:AD2:DAC", "TDM AD2:DAC" },
你可以把所有的值尝试一遍看是否影响。
cset "name='TDM Data Mux' AD1:AD2:DAC:NUL"
...
看了一下，不用全部试，用下面四个其中之一的值试一下就可以确认是不是这个值的问题。
{ "TDM Data Mux", "DAC:NUL:DAC:AD2", "TDM AD2:DAC" },
{ "TDM Data Mux", "DAC:NUL:AD2:DAC", "TDM AD2:DAC" },
{ "TDM Data Mux", "NUL:DAC:DAC:AD2", "TDM AD2:DAC" },
{ "TDM Data Mux", "NUL:DAC:AD2:DAC", "TDM AD2:DAC" },
如果没有用的话，试试把conf里原本开启的pcm1_out mix 0 codec_in0关掉，这个是控制录音进入路由的开关，但录音部分现在完全还没处理，有可能是它造成的问题。
//cset "name='pcm1_out mix 0 codec_in0 Switch' on"
cset "name='pcm1_out mix 0 codec_in0 Switch' off"
试了这4+1没用

使用aplay指定设备是能播放的，也许是我这软件配置问题
那可能是ALSA的问题了，widget route是完全通的，应该没有问题，ALSA我也没有弄得很懂，太多琐碎的东西了。又或者是玄学问题，哈哈。
据我所知ALSA会去找Master Playback Volume这个widget名，有空也可以试试我之前那样在源码手动改一个音量widget名（conf里也要对应改），不知道会不会起作用。
是软件问题，又莫名其妙好了。
以下是修改方案。这么做会导致设置无法测试左右声道，不过这功能应该没多少人用
/usr/share/pipewire/pipewire.conf
249行 Dummy-Driver 设备后面定义。并设置 cset "name='DAC1 Playback Volume' 175"
{ factory = spa-node-factory
args = {
factory.name = api.alsa.pcm.sink
node.name = "alsa_card.platfrom-cht-bsw-rt5659"
node.description = "PCM Device"
media.class = "Audio/Device"
api.alsa.path = "hw:0"
api.alsa.period-size = 1024
api.alsa.headroom = 0
api.alsa.disable-mmap = false
api.alsa.disable-batch = false
audio.format = "S16LE"
audio.rate = 48000
audio.channels = 2
audio.position = "FL,FR"
}
}
取消右扬声器注释之后，进系统选左还是右声道，两个扬声器都响。

使用左右声道分别静音的音乐文件，发现左声道两个都响，右声道两个扬声器都没声音
解决了，现在扬声器可以单独处理一个声道
如果你有兴趣把耳机功能也完善的话，可以研究下小米官方源码里\drivers\pinctrl\pinctrl-cherryview.c里部分代码
#define UART_JACK_SW_GPIO 357
#define UART0_RX_GPIO 403
#define UART0_TX_GPIO 408
int chv_enable_jack(int enable)
{
/* enable/disable jack */
chv_gpio_cfg_ctrl0(UART_JACK_SW_GPIO, CV_GPIO_TX_STAT,
enable ? 0 : 1);
/* Set UART0_DATAOUT */
chv_gpio_cfg_ctrl0(UART0_TX_GPIO, CV_GPIO_EN, enable);
if (enable) {
/* set to low */
chv_gpio_cfg_ctrl0(UART0_TX_GPIO, CV_GPIO_TX_STAT, 0);
}
/* set UART0_DATAIN */
chv_gpio_cfg_ctrl0(UART0_TX_GPIO, CV_GPIO_EN, enable);
if (enable) {
/* set to low */
chv_gpio_cfg_ctrl0(UART0_TX_GPIO, CV_GPIO_TX_STAT, 0);
}
pr_debug("%s %x, %x, %x\n", __func__,
chv_gpio_cfg_read(UART_JACK_SW_GPIO, CV_PADCTRL0_REG),
chv_gpio_cfg_read(UART0_TX_GPIO, CV_PADCTRL0_REG),
chv_gpio_cfg_read(UART0_RX_GPIO, CV_PADCTRL0_REG));
return 0;
}
EXPORT_SYMBOL_GPL(chv_enable_jack);
里面的gpio引脚号需要按照我上面讲的转换成500以上的。
pinctrl-cherryview.c (39.1 KB)
这部分变动太大了，还涉及内存地址读取。一些api参数换了，如：chv_gpio_reg与新的chv_padreg，还没查到参数struct intel_pinctrl原型
重新看了下电路图，发现那部分代码实际上是驱动一个旁接的uart芯片，应该是小米当初设计了串口来调试用的，并不影响耳机的连通，可以不用管它了。
所以理论上，去对比官方源码里\sound\soc\intel\board\cht_bl_dpcm_rt5672.c与\sound\soc\intel\board\cht_bl_dpcm_rt5659.c的差异，然后把把原版内核里cht_bsw_rt5672.c对应部分更改，并在ucm conf里配置耳机的widget route，应该就可以修复耳机功能了。
