I would like to know which file I can use to connect/enable DPAM widgets permanently so a simple aplay/record can work?

My environment is: - Yocto Linux Kernel 3.10 - (DTS based) - Max98090 Codec - imx6SL SoC

I thought about doing this in alsa.conf or asound.conf but I couldn't find a single example with DAPM widgets .

Thank you
