I have integrated wm8960 codec in place of tlv320 codec which is default present in phytec segin imx6ul board.
I made all the necessary changes in dts .And i can observe that i2cdetect also shows the UU at the at the address 1a which is the address of wm8960 codec .By this i confirmed that wm8960 codec driver is in use and by codec.
But after it is detected, if i am checking alsamixer and run the audio wav file , i am getting the error sound card not detected and alsamixer is not available.
please share the details where are the changes i should make to make the sound card detected, and which are the drivers responsible for codec and sound part.
Hi Dhanush
one can look at i.mx6ul wm8960 example on
imx6ul-14x14-evk.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel
and try to debug it using Figure 7-1. ALSA SoC Software Architecture
attached Linux Manual. Please pay attention to sect.7.1.2.4 Sound Card Information.

Hi Dhanush
wm8960 codec is working fine on nxp i.mx6ul evk board, one can try using images from
Issues with phytec software may be posted on phytec forum Dashboard - PHYTEC Wiki

Hi igorpadykov,
If during compilation in menuconfig i could not find the sound card driver
for wm8960 ,there is sound card driver for wm8962 ,now i can i enable the
sound card driver for wm8960.
since i didn't enable this sound card driver I could not access the
alsamixer and aplay command.Please suggest me the solution ASAP.
