Thanks for your attention and quick reply. I have another problem. I want to drive TLV320AIC23 codec to play and record audio. I Migrated from kernel 3.8 to 4.1, because kernel 3.8 dose not support this codec, and i couldn't add this codec to kernel 3.8. What is your idea? Is there any way to add this codec to kernel 3.8? It is ideal for me to use kernel 3.8, because of stability of this version.But if i can drive codec in kernel 4.1 it is not a too bad solution!
