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: omap_pcm_pointer It just won't send the frames.
Thank you for your help.
