Hi: It's been a lot since i posted this question, but i was finishing my studies at university, so i left this project appart... Now, i've already written an audio driver for PCM3168 codec, and followed the instructions in http://processors.wiki.ti.com/index.php/Sitara_Linux_Audio_DAC_Example#Creating_pcm5102a_hw_params_Function, but i'm stuck in making alsa work... something about "Broken configuration for this PCM: no configurations available" when i try to record... if someone has any information i would be very grateful Thanks
