snd_soc_register_component cannot find when compiling about ar9331-i2s-alsa HOT 5 CLOSED

Hi fastwave!

It seems you forgot to insmod the module which provides the symbols for snd_soc_register_dai. Maybe you forgot to insmod the kernel module soc-core.ko?

Hi fastwave!

Which codec do you use with your setup?

It seems you have dependencies to i2c and spi. Could you please test it with the wm8727 codec?. It is a very simple codec without any control interface.

Hi Franz,
I use wm8960 which need a I2C .Now the above issue has been resolved after installing some necessary .ko file ,such as opkg install kmod-regmap and insmod snd-soc-core.ko, all the modules you provided has been insert without error, so there is no issue in your package. Now I have an issue of i2c-gpio I don't know if you have seen this, thanks very much if you can help on it ,.I need I2C gpio bus but after installing i2c-gpio-custom.ko i2c-gpio.ko ,there are below error
[ 3744.770000] Custom GPIO-based I2C driver version 0.1.1
[ 7130.630000] i2c-gpio: probe of i2c-gpio.0 failed with error -16
