I am working on a project for car infotainment system, I have to record stereo audio using wm8960 audio codec which is used on imx6ulevk base board. On baseboard we are having one onboard mic audio input and one jack input for headset mic.
Using arecord command i can record audio which uses onboard mic (RINPUT2 -MAINMIC-MIC2(P) , RINPUT -MAINMIC-MIC2(N)). I want to record stereo audio by using both RINPUT CHANNEL AND LINPUT CHANNEL.
How to enable dual channel.
