We can't really tell people what the selection does because that depends on the external hardware. The A setting might be a headset mic, or a line in, or a builtin mic...
All we can do is say what the selection is called generically by the codec. So take the IN1L signal, on the codec it has two inputs "A" and "B". The IN1L Mux control has two settings "A" and "B". That seems clear.
So you're saying that you've got a mux on a single physical input which has two inputs? Are you sure that this is actually a mux and not some sort of mode setting that should be in platform data or DT - what do these settinngs actually correspond to? The routes in the driver look like there's two physical pins for each one of IN1L/R which the device can switch between for some reason which does correspond to a mux but that'd more normally be named IN1AL or similar.
Though if the left and right side need to be set to the same thing (which IIRC a previous version had code to check for and you did mention in your mail) all the time then why are there two separate muxes anyway?
