How to record audio with iMX6 Sabre SDP built-in microphones

The Sabre SDP has two digital microphones.  They are Analog Devices ADMP421B which are connected to a Wolfson WM8962 Codec.

What Linux command do I use to record audio? 

Alsa or gstreamer?  And how would I switch between built-n microphones to microphone input jack?

Any help would be appreciated.

Thank you.
