[FFmpeg-user] Command line to show channel label/position

[MrNice]

Hello there,

What is the best command line to get details about channels 
position/label in a multichannel audio file ?

I tried ffprobe but I get only

channels=6
channel_layout=5.1

not FR, FL, C, LFE, BL ...

BTW what is the best way to name this parameter ?
