Record mono audio from lineinl lineinr fminl fminr

Greetings

Does anybody knows how to utilize audio inputs linein and fm in and what distro is best suited for that job. My aim is to record 4 independent channels in mono 16 bit directly to ssd sata hard drive.

I can use for example usb sound cards with usb hub but is it possible to use line in.

Found some info on Banana PI Line-IN

Thanks , best regards
