Issues: WM8960 codec EVK not working
I almost working for this issue but got strange problem:The MCLK, TX_BCLK and TX_SYNC is working fine when I execute command aplay test.wav, but the key issue is TX_DATA is no any response, because I use the simple-sound-card and wm8960 driver to run this project, please give me some directions for debug the TX_DATA part, thanks a lot!
