Select one specific channel in source

[pabgn]

Hello,

I'm using an input source which contains 2 channels (Left + Right). I am able to get both or just one (channel 1) by using config.channels = 1;

Is there anyway to access only a specific channel (ex: number 2)?

It could also be helpful to work with both channels but being able to split them in the data incoming, but I've confirmed it comes mixed somehow...
