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
c# aplay sine.wav

在我安装模块时,有这样一个错误
# insmod snd-soc-tlv320aic3x-i2c.ko

下面是我的相关设备树配置

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
