TLV320AIC3104: 安装snd-soc-tlv320aic3x-i2c.ko模块失败，无法aplay音频

你好，我升级到linux5.15.71配置声卡的时候，选配了snd-soc-tlv320aic3x.ko 和 snd-soc-tlv320aic3x-i2c.ko 模块，安装完成后

ls /dev/snd/ by-path controlC0 pcmC0D0c pcmC0D0p timer  

但是安装完模块后 i2c命令无法使用，不安装模块时都是可以使用的

# i2cdump -y -f 0 0x18
No size specified (using byte-data access)
0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef
00: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX

无论是播放还是录制音频都是显示这种信息

在我安装模块时，有这样一个错误

请问我是哪里没配置，还有有什么配置错误呢？menuconfig里面选配那些

Amy Luo：

您好，

您在哪里找的的snd-soc-tlv320aic3x.ko 和 snd-soc-tlv320aic3x-i2c.ko？

看下面FAQ有提到TLV320AIC3104 驱动，看下是否有帮助：

[FAQ] Linux Drivers: Device drivers for AIC31xx/DAC31xx/AIC325x/AIC320x/AIC326x/AIC321x

,

ka ka：

这两个ko文件是我选配menuconfig编译成模块，板子上电后安装的。

,

ka ka：

这个链接的驱动文件安装后，显示找不到声卡。我编译我自己的内核，如果能找到声卡就无法使用i2ctool工具，也无法播放和录制。和声卡是冲突的，是不是我的设备树那里配置有问题呢，但是我没有查看到错误
