Hi, i'm new to alsa and i would like some advice on where to get information
about writing an ASoC driver it would be for the beagle board, since is the
board i have available. I have already made some progress initializing and
loading info to the codec via I2C, but I think there are still many things I
don't know.
I still don't know the exact way for playing via pcm with aplay or the order
of the callbacks. I have checked the web for info but not much about ASoC,
just the documentation with the linux kernel.

My driver actually tries to play with aplay, but gets stuck in : omap-pcm.c:
It just won't send the frames.

Thank you for your help.
