Hello All,

I try to run 2019CES demo#2 using m3ulcb.

I downloaded the image from this URL.

https://iot.bzh/download/public/2019/AGL_Images/m3ulcb/20190409133453/images/

I found that agl-service-audio-4a provided two apis by checking config.xml.

They are "ahl-4a" and "4a-hal-rcar-m3kf-unicens".

I wonder why there're two apis in one binding and how to implement?

Could you give me the source code for reference?

Thanks very much!
