Impedance of Input ? (Ohm, sweet...)

[fredvs]

Is it possible to retreive the Impedance (ohm) of the Inputs (mic , line) and to ajust it. (for example to have the same on line and mic). On major cards there is a +3db for mic, then maybe...

No, impedance is fixed, and it's hardware stuff - you can't change it from your application. Far as I know
