HI,
I directly placed "asound.conf" file in
"/cupcake/out/target/product/generic/system/etc" and generated a image which
I flashed into board. My asound.conf file is mentioned below. Kindly give me
some pointers If there is any syntax mistake or any mistake I have done.
I am working on i.MX31 PDK board, I am not very sure about the paramenters
which is passed here, Kindly correct me or suggest me .
