The only real solution is a hardware preamp. You can apply
the RIAA filter in software, but unless you start with a
*very* clean digital signal it's not a good idea to do so.
Neither a mic input, a line input or a high-Z instrument input
has the right combination of impedance and sensitivity for a
phono cartridge. Not using the right impedance will mean the
EQ will be wrong.
I do have an RIAA ladpsa plugin, let me known if you want it.
*If* you want to try without a real phono preamp the only
input type that *could* work is a high-Z instrument input,
with a 47k resistor in parallel. But the noise level could
be below par.
