[alsa-devel] Select source support in alsa soc

I am in a process of making a asoc driver for costum board. with OMAP3430 and twl4030 combination..

I have a driver now at a palce where i can play back with stereo headset and

record through line in cable.

I need some understanding of how can i give support for selecting output and input sources.

I have understood the way it is done in ALSA but i feel the sane should not be used in ALSA SOC frame work.

I would be thankful if someone can help me solve this issue.

Thanks, Neyo
